Performance Management Discrimination Risks in England and Wales explained, covering Equality Act 2010 protections, disability adjustments, unfair performance reviews, PIPs, tribunal claims, and employer responsibilities. A detailed guide to how performance systems can lead to discrimination claims and legal remedies.

Performance management is a routine feature of employment relationships. Employers use it to set objectives, monitor progress, conduct appraisals, and address underperformance through informal feedback or formal processes such as performance improvement plans (PIPs). While these systems are lawful and often necessary for business operations, they carry significant legal risk if applied in a discriminatory way.
In England and Wales, performance management is governed primarily by the Equality Act 2010, which prohibits discrimination, harassment, and victimisation in the workplace. Problems often arise where performance systems are inconsistent, poorly evidenced, or fail to take account of protected characteristics such as disability, sex, race, age, religion or belief, sexual orientation, pregnancy and maternity, and gender reassignment.
Disputes in this area frequently lead to employment tribunal claims, including discrimination, unfair dismissal, and breach of contract.
Legal Framework Governing Performance Management
Equality Act 2010 protections
The Equality Act 2010 makes it unlawful for employers to treat workers unfavourably because of a protected characteristic. This applies throughout performance management, including:
- Setting objectives
- Monitoring output
- Conducting appraisals
- Implementing PIPs
- Making promotion, pay, or dismissal decisions
Relevant types of discrimination include:
- Direct discrimination: less favourable treatment because of a protected characteristic
- Indirect discrimination: neutral rules that disadvantage a protected group without justification
- Discrimination arising from disability: unfavourable treatment linked to disability-related effects
- Failure to make reasonable adjustments: where disabled employees are placed at a disadvantage
- Harassment and victimisation: adverse treatment linked to complaints or protected traits
How Performance Management Creates Discrimination Risk
1. Biased or inconsistent performance assessments
Performance systems often rely on managerial judgment. This introduces risk where:
- Different managers apply different standards
- Subjective language is used without clear criteria
- Similar performance is rated differently across employees
- Feedback is influenced by stereotypes or assumptions
Acas guidance highlights the importance of consistent, objective assessment and regular documented feedback to reduce disputes and maintain fairness .
Where inconsistency correlates with a protected characteristic (for example, consistently lower ratings for a particular group), this may support an indirect discrimination claim.
2. Setting unrealistic or non-job-related targets
Performance objectives must be reasonable and linked to the role. Risks arise where:
- Targets are unachievable within normal working conditions
- Objectives change frequently without explanation
- Employees are not given adequate time or support
- Metrics do not reflect actual job duties
Tribunals may scrutinise whether performance expectations were genuinely attainable or effectively designed to justify disciplinary action.
3. Failure to adjust performance expectations for disability
Disability discrimination is one of the most common risk areas in performance management.
Employers must consider reasonable adjustments where a disabled employee is placed at a substantial disadvantage. This may include:
- Adjusting performance targets
- Extending deadlines
- Providing assistive tools or support
- Modifying working patterns or duties
Failure to adjust performance expectations may amount to:
- Failure to make reasonable adjustments
- Discrimination arising from disability under section 15 Equality Act 2010
Even where performance concerns are genuine, disciplining or dismissing without adjustments can be unlawful.
4. Performance management linked to sickness absence
Performance systems sometimes penalise absence-related issues. Risks include:
- Counting disability-related absence against performance ratings
- Penalising pregnancy-related sickness
- Treating medical leave as evidence of poor performance
- Applying attendance thresholds rigidly without adjustment
This can create indirect discrimination or disability-related discrimination if absence is connected to a protected characteristic.
5. Performance Improvement Plans (PIPs) used unfairly
PIPs are designed to support improvement, but legal risk increases where they are misused. Common issues include:
- Setting employees up to fail through unrealistic targets
- Providing insufficient time or support
- Lack of clear evidence of underperformance
- Escalation to dismissal without genuine opportunity to improve
Where a PIP is not genuinely supportive, tribunals may view subsequent dismissal as procedurally unfair or discriminatory.
6. Discriminatory feedback and workplace language
Even informal performance conversations can create liability if they involve:
- Stereotyping linked to protected characteristics
- Humiliating or hostile remarks
- Assumptions about capability based on age, gender, or ethnicity
- Comments linked to pregnancy, disability, or religion
If such behaviour creates a degrading or hostile environment, it may amount to harassment under the Equality Act 2010.
7. Victimisation during performance management
Victimisation occurs where an employee is treated badly because they have:
- Raised a discrimination complaint
- Supported a colleague's complaint
- Asserted Equality Act rights
In performance contexts, this may include:
- Sudden initiation of performance procedures after complaints
- Escalation of warnings following grievances
- Exclusion from opportunities after raising concerns
Tribunals assess whether there is a causal link between the protected act and the adverse treatment.
Employer Duties in Performance Management
Employers must ensure performance systems are legally compliant. Key responsibilities include:
- Using clear, objective performance criteria
- Keeping written records of reviews and decisions
- Ensuring consistent application across employees
- Providing training to managers on equality law
- Making reasonable adjustments where required
- Following fair procedures aligned with the Acas Code of Practice
Failure to follow fair procedures can support claims for unfair dismissal and increase compensation awards.
Employment Tribunal Claims Linked to Performance Management
Employees may bring claims where performance management is discriminatory or unfair. Common claims include:
- Direct discrimination
- Indirect discrimination
- Disability discrimination
- Harassment
- Victimisation
- Unfair dismissal
Tribunals consider:
- Whether performance concerns were evidenced
- Whether the employer acted reasonably
- Whether similar employees were treated differently
- Whether adjustments were considered
- Whether dismissal was a proportionate response
Compensation may include injury to feelings, loss of earnings, and aggravated damages in serious cases.
Time Limits and Early Conciliation
Most discrimination claims must be brought within three months less one day of the act complained of. Time limits are subject to extension through Acas Early Conciliation, which is mandatory before issuing a tribunal claim.
Delays in raising concerns can significantly affect legal outcomes.
Practical Steps Where Risks Arise
Where performance management may involve discrimination concerns, relevant steps often include:
- Requesting written clarification of performance concerns
- Keeping records of appraisals, emails, and objectives
- Identifying inconsistencies in treatment compared with colleagues
- Requesting reasonable adjustments where applicable
- Raising a formal grievance where appropriate
- Engaging in Acas Early Conciliation before tribunal action
These are procedural considerations and not legal advice.
Common Questions
Can poor performance justify dismissal even if discrimination is alleged?
Yes, but the employer must show both a genuine reason and a fair, non-discriminatory process.
Is subjective performance evaluation lawful?
Yes, but it must be supported by evidence and applied consistently.
Do employers have to adjust performance targets for disability?
Yes, where failure to do so places the employee at a substantial disadvantage and adjustments are reasonable.
Can performance management be used after a grievance?
Yes, but it must not be retaliatory or linked to the complaint itself.
Final Thoughts
Performance management is legally permissible but carries significant discrimination risk if applied inconsistently, subjectively, or without appropriate adjustments. The most common issues arise in disability-related performance concerns, inconsistent appraisal systems, and poorly managed performance improvement processes. Employers must ensure fairness, documentation, and compliance with the Equality Act 2010, while employees facing unfair treatment may have grounds for tribunal claims if discrimination can be evidenced.
