What is a performance improvement plan (PIP)?

Expert Answer

A Performance Improvement Plan (PIP) is a formal management tool used when an employee's performance falls below the required standard. It sets out clear expectations, measurable targets, and a defined timeframe for improvement. Used correctly, a PIP can turn around underperformance. Used incorrectly, it can expose your business to unfair dismissal claims.

When to Use a PIP

  • After informal conversations have failed to improve performance
  • When there's a capability issue (can't do the job) rather than a conduct issue (won't do the job)
  • Before considering dismissal for poor performance
  • After a probation review identifies concerns

What a PIP Should Include

  • Specific performance gaps — exactly where performance falls short, with evidence
  • Expected standards — what "good" looks like, with measurable targets
  • Support offered — training, mentoring, adjusted workload, regular check-ins
  • Review dates — typically weekly or fortnightly during the PIP period
  • Timeframe — usually 4-12 weeks depending on the role and issues
  • Consequences — what happens if improvement isn't achieved (e.g., formal capability hearing)

Legal Considerations

A PIP is not a legal requirement, but it's an essential part of a fair process. If you later need to dismiss for poor performance, a tribunal will want to see that you:

  • Clearly communicated the expected standards
  • Gave the employee a reasonable opportunity to improve
  • Provided appropriate support
  • Followed a fair procedure (aligned with the ACAS Code of Practice)
