Inconsistent decision-making has emerged as a critical yet often overlooked challenge within UK workplaces, eroding trust, compromising fairness, and hindering organisational performance. Whether manifesting in unequal application of policies, variable management styles, or erratic performance reviews, this lack of standardisation creates a culture of uncertainty and perceived inequity among employees. For UK businesses, the ramifications extend beyond diminished morale to include tangible risks such as increased employment tribunal claims, talent attrition, and reduced productivity.

Recognising Patterns of Inconsistent Decision-Making
Common Inconsistency Indicators
- Policy application variations: Different standards or rules applied to similar situations
- Unpredictable outcomes: Similar requests or situations receiving dramatically different responses
- Changing priorities: Frequent, unexplained shifts in organisational focus and direction
- Communication breakdowns: Decisions made without clear rationale or proper communication
Impactful Examples
- Approval inconsistencies: Similar requests approved for some team members but denied for others
- Performance evaluation disparities: Different standards applied to comparable work quality
- Flexibility contradictions: Variable application of flexible working policies
- Promotion inconsistencies: Unclear or shifting criteria for advancement opportunities
Legal Framework and Employment Rights
Equality Act 2010 Considerations
The Equality Act 2010 provides protection when inconsistent decisions:
- Relate to protected characteristics including age, disability, gender, race, religion, or sexual orientation (Legislation- GOV.UK)
- Create discriminatory outcomes through unequal treatment
- Result in indirect discrimination through inconsistently applied policies
Employment Rights Act 1996 Considerations
For employees with over two years' service, a dismissal can be found unfair if the employer acted unreasonably.
- Inconsistent Disciplinary Action: This is a classic example. If an employer dismisses Employee A for misconduct but only gives a warning to Employee B for the same or similar misconduct, the dismissal of Employee A is likely to be deemed unfair. The employer would need to show a clear and justified reason for the difference in treatment.
- Capability/Performance: Similarly, applying performance standards inconsistently can render a dismissal for capability unfair.
Strategies for Managing Inconsistent Decisions
When facing inconsistent or unfair decisions at work, your legal standing depends heavily on the reason behind the inconsistency. Protection from discrimination, which includes biased or inconsistent treatment based on any of the nine Protected Characteristics, is immediate. This applies from your first day of employment, regardless of your length of service. Agency workers in the same workplace may, however, find it harder to claim protection as they are not direct employees.
The nine Protected Characteristics are: age, disability, gender reassignment, marriage/civil partnership, pregnancy/maternity, race, religion/belief, sex, and sexual orientation.
If the inconsistent treatment is unrelated to discrimination—for example, unfair application of policies, arbitrary disciplinary actions, or inconsistent performance management—you are typically only protected from unfair dismissal after completing two years of service.
Therefore, raising a formal issue about inconsistent decisions carries considerable risk unless your case is clearly linked to discrimination, or you have at least two years of service. Without the anchor of either a Protected Characteristic or sufficient tenure, you may have limited legal recourse.
Step 1: Self-Check & Gather Evidence (Before Taking Action)
- Confirm the Inconsistency: Are the situations truly comparable? Consider job roles, seniority, timing, and personal history (e.g., a final warning). Objectively assess if you might be missing a valid, non-discriminatory reason for the difference.
- Document Everything: Create a private, detailed record. Note:
- Your Situation: Dates, what happened, the decision made, who made it, and the reason given.
- The Comparator: Details of the similar situation where a different (more favourable) decision was made. Who, what, when, and the outcome.
- Policy References: Note any relevant company policies (e.g., disciplinary, promotion, flexible working) that support your view of inconsistency.
- Identify the Impact: How has this inconsistency harmed you? (e.g., financial loss, missed opportunity, reputational damage, stress).
Step 2: Choose Your Initial Approach
Option A: Informal Discussion (Often the best first step)
- Purpose: To seek clarification, not to accuse. Frame it as you seeking to understand the decision-making process.
- Scripting: Use neutral, non-confrontational language.
- "Hi [Manager], I'd like to better understand the decision on [X]. I was under the impression that the policy/usual approach was [Y], as in the case of [Colleague's situation]. Could you help me understand the difference so I can better meet expectations moving forward?"
- Outcome: This gives the manager a chance to explain a rationale you may not know or to correct an oversight. Document their response.
Option B: Raise a Formal Grievance (If informal fails or the issue is serious)
- When to Use: If the informal chat is dismissed, if the inconsistency is blatant and harmful, or if you suspect it may be linked to a protected characteristic (e.g., race, gender, age).
- Process: Follow your company's formal grievance procedure to the letter. This is usually found in your contract, staff handbook, or intranet.
- Your Submission: Submit your grievance in writing. Be factual, reference your evidence, state the relevant policy, and clearly explain how the inconsistent treatment has affected you. State the resolution you seek (e.g., a fair re-evaluation, an apology, a policy review).
Step 3: Escalation and External Options
If internal processes fail to resolve the issue, you have several external routes, depending on the nature of the inconsistency:
- Contact ACAS: The Advisory, Conciliation and Arbitration Service offers free, confidential early conciliation. They can act as a neutral mediator between you and your employer before you consider a tribunal claim. This is a mandatory step for most tribunal claims.
- Seek Legal Advice: Consult an employment solicitor for formal advice, especially if you're considering leaving your job or suspect discrimination. Many offer a free initial consultation. There are also more affordable advice services for self-representation such as Valla.
- Employment Tribunal Claim: This is the final legal recourse. Potential claims linked to inconsistency include:
- Unfair Dismissal (if you have 2+ years service and are dismissed inconsistently).
- Discrimination under the Equality Act 2010 (no length of service required). Inconsistency is powerful evidence here.
- Constructive Dismissal (if the inconsistency, combined with other failings, breaches your contract so severely you feel forced to resign).
