The core idea

Leader–Member Exchange, or LMX, focuses on the relationship between a leader and each colleague rather than only the leader’s general style. Relationships can differ in trust, mutual obligation and access to support. The research developed from earlier work on vertical dyad linkages. Differences can become an in-group/out-group problem when some employees consistently receive better information, attention or opportunities. The practical aim is not to formalise favourites, but to examine how high-quality working relationships can become more widely available.

Using it in practice

Review who receives stretch work, feedback, informal information and introductions. Compare patterns with relevant job needs and transparent criteria. Ask whether remote workers, night shifts, part-time colleagues or newer staff have equivalent routes to support. HR should investigate how opportunities are allocated rather than assuming that a good average engagement score demonstrates fair treatment. Use confidential employee accounts alongside records of decisions.

An example, not a reported case

Worked example · illustrative

A fictional manager allocates development assignments to the employees they speak with most often on the day shift. Night-shift colleagues appear less interested because they hear about opportunities late. HR helps the manager publish opportunities, discuss aspirations with every colleague and use clear selection criteria. Follow-up considers access, uptake and experience across shifts. The aim is to improve the process, not to force every working relationship to feel personally identical.

What to watch for

Relationship quality and performance can influence each other, making simple causal stories unreliable. Equal respect does not require identical assignments, but differences need defensible reasons and fair access. Do not ask employees to gain favour through unpaid availability or personal similarity. The model should prompt scrutiny of power and opportunity, not justify a permanent inner circle.

Map opportunities rather than popularity

List recent development tasks, informal briefings and feedback conversations. Ask who was considered and why. Check whether relevant capability was assessed or merely assumed from familiarity. Keep the exercise focused on work decisions rather than rating personal likeability.

Create reliable contact

Agree a reasonable rhythm of individual conversations and make it accessible across shifts and locations. Ask about goals, obstacles and feedback preferences. A scheduled conversation is not sufficient by itself, but it reduces dependence on chance encounters and makes a route to support visible.

Explain differentiated support

People may need different amounts or kinds of assistance. Explain the job-related reasoning and review it with them. Distinguish a justified adjustment from a pattern in which one person receives all the interesting work and another only routine tasks. Invite challenge to the allocation process.

Evaluate fairness over time

Track whether opportunities are advertised, who applies, who is selected and what happens afterward. Interpret small groups cautiously and avoid exposing confidential comments. Combine records with employee accounts so that a formally equal process does not conceal barriers in how people hear about or access it.

Take it into your next conversation

Three useful questions.

  1. What does this particular situation need from the leader?
  2. How will colleagues experience the approach, including those with less influence?
  3. What evidence would tell us to continue, adjust or stop?
