HRM Theories and Conceptual Frameworks

Introduction

A dissertation in Human Resource Management (HRM) is not simply a description of workplace events. It is an evidence-based explanation of a problem. Theories help the researcher explain why relationships may exist, while conceptual frameworks translate those explanations into a structured research model. A well-designed framework identifies the main constructs, proposes relationships among them, and guides the collection and interpretation of evidence.

For example, a researcher studying employee turnover may observe that employees leave when they experience low job satisfaction. Observation alone, however, does not explain whether dissatisfaction is caused by poor supervision, inadequate rewards, limited career opportunities, excessive workload, or a combination of factors. HRM, organisational behaviour and employment theories provide alternative explanations. The researcher must then select the theory—or combination of theories—that best fits the research problem and context.

This chapter explains how to select, evaluate and apply theories in an undergraduate HRM dissertation. It distinguishes theories from models and conceptual frameworks, examines influential HRM and organisational behaviour perspectives, explains constructs and relationships, and demonstrates how to construct a defensible conceptual model.

1. Theory, Model and Conceptual Framework

1.1 What is a theory?

A theory is a logically connected set of concepts and propositions that explains a phenomenon and predicts relationships among its elements. Theory is more than a personal opinion or a list of factors. It provides a rationale for why a relationship should exist.

A theory normally contains:

• Concepts or constructs: abstract ideas such as trust, commitment or perceived organisational support.
• Definitions: statements specifying what each construct means.
• Propositions: theoretically reasoned statements about relationships.
• Boundary conditions: circumstances in which the explanation may or may not apply.
• Assumptions: beliefs about people, organisations or social relationships underlying the theory.

Theories may be broad, such as social exchange theory, or narrow, such as a model explaining how feedback affects performance. A dissertation does not need to test an entire grand theory. It usually applies a selected part of a theory to a defined population and context.

1.2 Models and conceptual frameworks

A model is a simplified representation of a phenomenon. It may be verbal, mathematical or diagrammatic. A conceptual framework is the researcher’s organised representation of the constructs and relationships relevant to a particular study. It is normally derived from theory, prior research and the characteristics of the research setting.

The distinction is important:

A framework should neither reproduce a theory without adaptation nor become a disconnected collection of variables. Each proposed relationship should have a clear theoretical and empirical justification.

2. Important Constructs and Relationships

2.1 Constructs and variables

A construct is an abstract concept that cannot usually be observed directly. Examples include employee engagement, organisational justice and psychological safety. A variable is an observable or measurable representation of a construct. For instance, responses to several survey items may be used to measure perceived organisational support.

Constructs may be:

• Latent: inferred from several indicators, such as engagement.
• Observed: directly recorded, such as age, salary or absence days.
• Individual-level: located at the employee level.
• Group-level: located at team or department level.
• Organisational-level: located at the organisation level.

Researchers must avoid treating related concepts as identical. Job satisfaction, engagement and organisational commitment overlap, but they are not interchangeable. Job satisfaction concerns evaluation of one’s job; engagement generally concerns energetic and cognitive involvement in work; commitment concerns attachment to the organisation or another target.

2.2 Types of variables

The following roles are common in HRM research:

• Independent variable (IV): a presumed explanatory factor, such as training quality.
• Dependent variable (DV): the outcome to be explained, such as performance or intention to leave.
• Mediator: explains how or why an independent variable affects an outcome.
• Moderator: changes the strength or direction of a relationship.
• Control variable: a factor included to reduce alternative explanations, such as tenure or job level.

Consider the relationship: supportive leadership → employee engagement → performance. Supportive leadership is the independent variable, performance is the dependent variable, and engagement is a mediator. If the relationship is stronger for permanent employees than temporary employees, employment status may be a moderator.

A mediation claim concerns a process:

Here, X is the independent variable, M is the mediator and Y is the dependent variable. A moderation claim concerns conditional strength:

Here, Z is the moderator. These are conceptual relationships, not automatic proof of causation. Causal interpretation requires appropriate design, temporal ordering, measurement and control of competing explanations.

2.3 Definitions and operationalisation

A conceptual definition explains the meaning of a construct. An operational definition explains how it will be measured or identified in the study.

For example:

• Conceptual definition: Employee engagement is a positive, work-related state involving energy, dedication and absorption.
• Operational definition: Engagement is measured using respondents’ scores on a validated multi-item scale.

A strong operationalisation should address content coverage, clarity, reliability and validity. Researchers should also state whether a construct is reflective or formative. In a reflective measure, indicators are viewed as effects of the underlying construct. In a formative measure, indicators combine to create the construct. This distinction affects scale design and analysis.

3. Major HRM and Organisational Behaviour Theories

3.1 Resource-Based View of the firm

The Resource-Based View (RBV) explains competitive advantage through valuable organisational resources and capabilities. Human resources may contribute to sustained advantage when employee knowledge, skills, relationships and routines are valuable, relatively rare, difficult to imitate and not easily substituted.

In HRM research, RBV supports the argument that practices such as selective recruitment, development, knowledge sharing and performance management can build human capital and organisational capability. A possible framework is:

High-involvement HR practices → employee skills and motivation → organisational performance

The theory is useful for strategic HRM studies, but it has limitations. It may treat employees primarily as resources, understate employee agency and overlook power, equality and ethical concerns. It can also be difficult to demonstrate that a capability is genuinely rare or inimitable. Researchers should therefore avoid claiming that every HR practice creates competitive advantage.

3.2 Human Capital Theory

Human Capital Theory views education, training, experience and health as investments that enhance productive capabilities. Employers may benefit through improved performance, innovation and adaptability, while employees may benefit through employability and earnings.

The theory is appropriate for research on training, career development, employability and returns to education. However, it should be applied critically. Performance is not determined by individual capability alone; technology, job design, leadership and organisational opportunity also matter. Human capital language may also obscure inequalities when workers receive unequal access to development.

3.3 Ability–Motivation–Opportunity framework

The Ability–Motivation–Opportunity (AMO) framework proposes that performance is influenced by:

• Ability: knowledge, skills and competence;
• Motivation: willingness and incentive to exert effort;
• Opportunity: the chance to participate, contribute and use one’s capability.

HR practices can be mapped to these dimensions. Recruitment and training develop ability; rewards and recognition influence motivation; participation, autonomy and information sharing create opportunity.

A simplified conceptual expression is:

This is not a universal mathematical production equation. It indicates that performance is a function of the three conditions and that a serious deficiency in any one may restrict outcomes. The framework is valuable because it prevents the researcher from attributing poor performance solely to employee motivation. Its limitation is that the three components may overlap and that the framework does not, by itself, specify the exact mechanisms or measurement methods.

3.4 Social Exchange Theory

Social Exchange Theory explains workplace relationships through reciprocal exchanges. When employees perceive that the organisation treats them fairly, supports them and fulfils its obligations, they may feel an obligation to reciprocate through commitment, citizenship behaviour or effort.

This theory underpins research on perceived organisational support, psychological contracts, leader–member exchange and employee engagement. A typical relationship is:

Perceived organisational support → felt obligation → affective commitment

The theory requires careful attention to the exchange partner. Employees may distinguish between the organisation, supervisor, team and individual colleagues. Reciprocity is not always immediate or equivalent, and employees may respond negatively when they perceive exploitation or broken promises. Cultural expectations about reciprocity may also differ.

3.5 Psychological Contract Theory

The psychological contract refers to an employee’s beliefs about mutual obligations between the employee and employer. It is not the same as the formal employment contract. A perceived breach occurs when the employee believes that the organisation has failed to fulfil an important promise or obligation. The resulting violation may affect trust, satisfaction, commitment and turnover intention.

This theory is useful in research on organisational change, flexible work, career promises, job security and restructuring. The researcher must distinguish breach, which is a cognitive judgement, from violation, which is the emotional reaction to that judgement. Perceptions are central; an organisation may believe it has fulfilled an obligation while employees perceive otherwise.

3.6 Job Demands–Resources model

The Job Demands–Resources (JD–R) model distinguishes between:

• Job demands: aspects of work requiring sustained physical, emotional or cognitive effort, such as workload, role conflict or emotional labour.
• Job resources: aspects that help employees achieve goals, reduce demands or stimulate growth, such as autonomy, supervisor support and feedback.

The model proposes two broad processes. Excessive demands may contribute to strain and burnout, while resources may encourage engagement and motivation. Resources may also buffer the effects of demands.

A framework might therefore propose:

Workload → burnout → turnover intention

and

Supervisor support moderates the relationship between workload and burnout.

The JD–R model is flexible and suitable for many occupations. Its flexibility is also a weakness: almost any work characteristic can be classified as a demand or resource, so definitions must be specific. Researchers should not assume that a resource is universally beneficial; autonomy, for example, may become burdensome when employees lack capability or support.

3.7 Goal-Setting Theory

Goal-Setting Theory proposes that specific and challenging goals can improve performance when individuals accept the goals, receive feedback and possess the capability to perform. It supports research on performance management, appraisal, incentives and target-setting.

The theory also identifies risks. Excessive or poorly designed targets may encourage gaming, unethical conduct, excessive risk-taking or neglect of unmeasured tasks. Goal-setting research should therefore examine goal quality, participation, feedback and unintended consequences rather than assuming that more demanding goals are always better.

3.8 Organisational Justice Theory

Organisational justice concerns employees’ perceptions of fairness. Common dimensions include:

• Distributive justice: fairness of outcomes such as pay or promotion.
• Procedural justice: fairness of the process used to reach decisions.
• Interactional justice: respectful and dignified treatment.
• Informational justice: adequacy and honesty of explanations.

Justice theory is relevant to pay, selection, promotion, disciplinary action, redundancy and performance appraisal. It helps explain why an unfavourable outcome may nevertheless be accepted when the process is transparent and respectful. However, justice perceptions are subjective and may be shaped by comparison groups, culture and power relationships.

3.9 Employment relations and pluralist perspectives

Unitary perspectives tend to view the organisation as a team with shared interests. Pluralist perspectives recognise legitimate differences between employers and employees and view collective representation and negotiation as normal features of employment. Radical or critical perspectives emphasise power, control, inequality and the political economy of work.

These perspectives affect research questions. A unitary study might ask how communication increases commitment. A pluralist study might ask how employee voice influences the settlement of competing interests. A critical study might examine how algorithmic management intensifies surveillance or transfers risk to workers.

No single perspective is automatically correct. The appropriate choice depends on the research problem. A dissertation examining fairness, union participation, precarious work or workplace surveillance should not rely exclusively on theories that assume harmonious interests.

4. Selecting and Critically Applying Theory

Theory selection should be purposeful rather than decorative. A theory is relevant when it explains the central problem, fits the level of analysis, supports the proposed relationships and is compatible with the research context.

A practical selection process is:

1. Define the problem: State what is happening, to whom, where and why it matters.
2. Identify the outcome: Clarify whether the study concerns performance, retention, wellbeing, inclusion, voice or another outcome.
3. Review competing explanations: Consider individual, relational, organisational and institutional explanations.
4. Compare theories: Assess assumptions, constructs, mechanisms, boundary conditions and empirical support.
5. Select a primary lens: Choose the theory that provides the strongest explanation.
6. Add complementary theory cautiously: Combine theories only when their assumptions are compatible and each contributes a distinct explanation.
7. Define constructs and relationships: Explain precisely what will be examined.
8. Develop the framework: Represent the proposed relationships in a diagram and narrative.
9. Operationalise constructs: Identify suitable indicators and data sources.
10. State limitations: Explain what the framework cannot explain.

A critical literature review does not merely report that “Author A found a positive relationship.” It asks whether the finding applies to the present population, whether measurement is sound, whether the relationship is causal, and whether alternative explanations remain.

5. Developing a Conceptual Framework

5.1 From research problem to framework

Suppose the research problem is: “Why do early-career employees in a public organisation report an intention to leave?” A preliminary review may identify career development, supervisor support, workload and organisational justice as possible influences. The researcher must avoid placing all four variables into a diagram without logic.

A theory-driven framework might propose:

• Human Capital Theory: development opportunities increase perceived career value.
• Social Exchange Theory: supervisor support creates reciprocal commitment.
• JD–R: workload increases strain, while support acts as a resource.
• Justice Theory: fair promotion procedures influence retention attitudes.

The framework must then narrow the study. A manageable dissertation might examine whether supervisor support and career development predict turnover intention, with organisational commitment as a mediator and workload as a control variable.

Figure: Illustrative conceptual framework for examining turnover intention. Solid arrows indicate proposed primary paths; dashed arrows indicate direct or control relationships requiring explicit justification.

5.2 Propositions and hypotheses

A proposition is a theoretically informed statement that may be explored qualitatively or conceptually. A hypothesis is a testable prediction, often expressed in quantitative research.

Examples include:

• H1: Perceived career development opportunities are negatively associated with turnover intention.
• H2: Supervisor support is positively associated with organisational commitment.
• H3: Organisational commitment mediates the relationship between supervisor support and turnover intention.

A good hypothesis identifies the constructs, direction and population. It should not include unsupported causal language when the design is cross-sectional. In that case, “is associated with” may be more defensible than “causes.”

5.3 Levels of analysis

A common conceptual error is mixing levels. Individual perceptions cannot automatically be treated as organisational properties. If the question concerns team climate, data may need to be collected from several members of each team and aggregated using appropriate evidence. Similarly, an organisation-level HR policy may be experienced differently by employees.

The framework, sampling strategy and analysis must align. A study claiming team-level effects should not rely only on one employee per team. A study of organisational policy should specify whether the policy is formally documented, implemented by managers or perceived by employees.

6. Applied Case: Flexible Work and Employee Wellbeing

Background

The following is a fictional illustrative case. Meridian Services, a 600-employee professional services organisation, introduced hybrid working. Senior managers believed flexibility would improve retention, while some supervisors reported declining collaboration. Employees differed in access to suitable home offices, technology and caring support.

Problem

The organisation wished to understand why hybrid work improved wellbeing for some employees but increased stress and isolation for others. A simple claim that “flexible work is beneficial” would ignore variation in job demands and resources.

Analysis through theory

The JD–R model identifies commuting reduction and autonomy as possible resources, but home-working distractions, blurred boundaries and digital overload as possible demands. Social Exchange Theory suggests that trust and perceived organisational support may encourage employees to reciprocate with commitment. Organisational Justice Theory raises questions about whether hybrid-work eligibility is distributed fairly across occupational groups.

A suitable framework might propose:

• autonomy and supervisor support increase wellbeing;
• digital overload increases exhaustion;
• psychological safety mediates the relationship between supervisor support and wellbeing;
• job type moderates the relationship between flexibility and wellbeing;
• perceived fairness influences acceptance of unequal access.

Approach and possible solution

The organisation could use a mixed-method design. A survey may measure autonomy, support, digital overload, psychological safety and wellbeing. Interviews could explore how employees interpret flexibility and fairness. HR records might provide contextual information about absence, turnover and job category, subject to privacy safeguards.

Interventions should not be based solely on individual resilience training. They may include clear availability norms, manager training, equitable access criteria, team coordination practices, workload review and confidential channels for reporting disadvantage.

Outcome and learning points

The likely outcome is not a universal answer but a differentiated policy. Flexible work may benefit employees when autonomy is accompanied by resources, manageable workload and supportive leadership. The case demonstrates that a conceptual framework helps connect theory to measurement and intervention. It also shows why context, power and distributional effects must be considered alongside efficiency.

7. Limitations, Ethics and Contemporary Developments

Theories simplify reality. A framework may omit variables because of limited time, access or dissertation scope. Cross-sectional designs may show association without establishing temporal sequence. Self-report measures may be affected by common-method bias, social desirability or fear of disclosure. Researchers should acknowledge these limitations rather than presenting a neat framework as a complete explanation.

Ethically, HR researchers must protect confidentiality, obtain informed consent and avoid collecting unnecessary sensitive information. Participants may fear that managers will identify their responses. Data should be securely stored, access limited and reporting aggregated where possible. Researchers should not use a framework to justify predetermined managerial decisions or conceal discriminatory outcomes.

Technology creates new theoretical questions. Artificial intelligence may support recruitment, scheduling, performance monitoring and learning recommendations, but it can also reproduce historical bias, reduce transparency and intensify surveillance. A technology-focused framework may combine Human Capital Theory with justice and employment-relations perspectives, asking not only whether an AI system improves efficiency but also who benefits, who bears risk and how decisions can be challenged.

Contemporary HRM research increasingly examines employee experience, inclusion, sustainability, remote and platform work, algorithmic management, wellbeing and the changing employment relationship. These topics require theoretical pluralism. For instance, a study of gig work may need to consider human capital, job demands, psychological contracts, power and institutional regulation rather than relying on a single individual-level theory.

Best Practices for Dissertation Frameworks

A strong framework should:

• begin with a clearly delimited research problem;
• use a small number of central constructs;
• define every construct conceptually and operationally;
• distinguish correlation from causation;
• identify the level of analysis;
• justify each arrow in the diagram;
• state mediators, moderators and controls explicitly;
• reflect the actual population and context;
• use validated measures where appropriate;
• consider alternative explanations and unintended effects;
• align theory, questions, methods and analysis;
• acknowledge boundaries and limitations.

A weak framework commonly contains too many variables, unexplained arrows, overlapping constructs, unsupported hypotheses or theories cited only in the introduction. The diagram should be the conclusion of reasoning, not a substitute for reasoning.

Chapter Summary

HRM theories provide explanations of workplace phenomena, while models simplify those explanations and conceptual frameworks adapt them to a particular dissertation. Core constructs must be clearly defined and distinguished from their measures. Independent, dependent, mediating, moderating and control variables play different analytical roles.

The Resource-Based View and Human Capital Theory explain how people and capabilities may create value. The AMO framework links ability, motivation and opportunity to performance. Social Exchange Theory and Psychological Contract Theory explain reciprocity, support and perceived obligations. The JD–R model examines the balance between work demands and resources. Goal-Setting Theory informs performance management, while Organisational Justice Theory addresses fairness. Employment-relations perspectives add attention to conflict, representation, power and inequality.

Theory selection should be driven by the research problem, level of analysis and context. A defensible conceptual framework follows from critical literature review, defines constructs, justifies relationships, identifies boundary conditions and aligns with the proposed method. Frameworks must also recognise ethical issues, limitations, employee agency and the possible effects of technology and AI.
