Managing Poor Performance: Employer's Guide
How to address underperformance fairly. Performance management processes, improvement plans, when performance becomes a disciplinary issue, and avoiding claims.
Managing underperformance is one of the most common challenges employers face. Done well, it improves or resolves the situation. Done poorly, it leads to claims.
Performance vs Conduct
Performance (Capability)
- Not meeting required standards
- Despite trying
- Due to ability, skills, or aptitude
- Requires support and training
- Use performance management process
Conduct (Misconduct)
- Deliberate misbehaviour
- Negligence or carelessness
- Breaking rules
- Requires disciplinary process
- Different legal considerations
Overlapping Issues
Sometimes behaviour looks like both:
- Persistent lateness (conduct or performance?)
- Careless errors (negligence or inability?)
Consider the real reason - is it "won't" or "can't"?
Identifying Performance Issues
Signs of Underperformance
- Missing targets or deadlines
- Quality problems
- Customer complaints
- Errors and mistakes
- Inability to learn new tasks
- Failure to meet job requirements
Before Acting
Check:
- Are expectations clear?
- Have they had proper training?
- Do they have the resources needed?
- Are there external factors?
- Is the standard reasonable?
The Performance Management Process
Stage 1: Informal Discussion
Purpose: Address issues early.
Approach:
- Private conversation
- Explain concerns clearly
- Listen to their perspective
- Agree what needs to improve
- Offer support
- Set review date
Document: Note of discussion, but not formal warning.
Stage 2: Formal Performance Review
If informal approach doesn't work:
Meeting:
- Give notice of meeting
- Right to be accompanied
- Explain concerns with specific examples
- Give opportunity to respond
- Consider their explanation
Outcome:
- First written warning (if appropriate)
- Improvement plan
- Support measures
- Review period
- Consequences of no improvement
Stage 3: Final Written Warning
If insufficient improvement after first warning:
- Further formal meeting
- Review progress (or lack of)
- Final written warning
- Clear statement that dismissal may follow
- Further review period
Stage 4: Dismissal Meeting
If still no improvement:
- Formal meeting
- Right to be accompanied
- Review all stages of process
- Consider their representations
- Make decision
- Right of appeal
Performance Improvement Plans (PIPs)
What to Include
-
Specific areas for improvement
- Clear, measurable objectives
- Current performance level
- Required performance level
-
Support provided
- Training
- Coaching
- Resources
- Regular check-ins
-
Timescales
- Review dates
- Overall PIP length
- Milestones
-
Consequences
- What happens if improvement achieved
- What happens if not
Example PIP Objectives
Vague: "Improve customer service skills."
Better: "Achieve customer satisfaction score of 80%+ (currently 65%). Complete customer service training by [date]. Reduce complaint rate from 5% to under 2% by [date]."
PIP Duration
Typical durations:
- Simple role: 4-8 weeks
- Complex role: 2-3 months
- Senior role: 3-6 months
Factors to consider:
- Nature of performance issues
- How long performance has been poor
- Time needed to demonstrate improvement
- Training requirements
Support During Performance Management
Types of Support
- Training (specific skills)
- Coaching or mentoring
- Regular feedback sessions
- Reduced workload temporarily
- Additional resources
- Changed responsibilities
Why Support Matters
For fairness: Shows you gave them chance to improve.
For defence: Evidence you acted reasonably.
For outcomes: Support may actually fix the problem.
Documentation
What to Record
- Performance concerns (specific examples)
- Meetings held (notes of discussions)
- Expectations communicated
- Support provided
- Progress reviews
- Warnings issued
- Final decision
Why It Matters
Good records:
- Show fair process followed
- Evidence expectations were clear
- Demonstrate support was given
- Defend against unfair dismissal claim
Common Scenarios
Scenario 1: New Starter Struggling
Three months in, new employee not meeting standards.
Approach:
- Extend probation if contract allows
- Provide additional training
- Clear feedback on gaps
- Regular reviews
- Consider if role is right for them
Scenario 2: Long-Serving Employee Decline
Previously good performer, now struggling.
Consider:
- Has something changed?
- Health issues?
- Personal problems?
- Changed job requirements?
- Offer support before formal process
Scenario 3: Attitude Problem
Employee capable but unwilling to try.
Consider:
- Is this really conduct, not capability?
- Address underlying issues
- May need disciplinary approach if deliberate
Scenario 4: Performance Across Team
Several team members underperforming.
Consider:
- Is the problem management or training?
- Are standards realistic?
- Consider team-wide approach
- May not be individual failure
Dismissal for Poor Performance
Fair Dismissal Requirements
- Genuine capability issue: Real performance shortfall
- Warnings given: Employee knew consequence of no improvement
- Opportunity to improve: Reasonable time and support
- Fair procedure: Meetings, right to be accompanied, appeal
- Reasonable decision: Dismissal in range of reasonable responses
What Makes Dismissal Unfair
- No warning that dismissal was possible
- Inadequate time to improve
- No support or training offered
- Procedural failures
- No opportunity to respond
- Inconsistent treatment
Alternatives to Dismissal
Consider before dismissing:
- Demotion (with agreement)
- Transfer to different role
- Reduced responsibilities
- Further extension
But don't keep someone indefinitely who can't do the job.
Appeal Process
Right of Appeal
Employee should have right to appeal dismissal.
Appeal Hearing
- Different manager than original decision-maker
- Review process and decision
- Consider new information
- Can uphold, overturn, or modify
Legal Considerations
Unfair Dismissal
After 2 years' service:
- Capability is potentially fair reason
- Must follow fair process
- Tribunal tests reasonableness
Discrimination
Watch for:
- Performance issues linked to disability (need adjustments)
- Different treatment of protected groups
- Performance management as cover for discrimination
Constructive Dismissal
Avoid:
- Humiliating the employee
- Setting impossible targets
- Treating them differently without reason
- Creating hostile environment

Frequently Asked Questions
- Is poor performance misconduct?
- Generally no. Performance (capability) and conduct are different concepts. Poor performance is usually inability to meet standards despite trying. Misconduct is deliberate misbehaviour or negligence. Use capability procedures for performance, disciplinary for conduct.
- How long should I give someone to improve their performance?
- Long enough to be reasonable given the role and nature of underperformance. A few weeks to a few months is typical. Consider how long they've been in role, training provided, complexity of issues, and whether improvement is possible with support.
- Can I dismiss someone for poor performance?
- Yes, but only after following a fair process. You must identify the problem, explain expectations, give them opportunity and support to improve, review progress, warn of consequences, and only dismiss if they fail to improve. Dismissal without process is likely unfair.
