Unfair dismissal is one of the most significant employment law risks that UK employers face, yet many founders have only a vague understanding of what it means, when it applies, and what the consequences of a successful claim can be. Understanding the basics of unfair dismissal protection is essential for any employer who may at some point need to end an employment relationship.
Unfair dismissal is the legal right of qualifying employees to challenge a dismissal they consider unjust or improperly handled at an employment tribunal. To dismiss fairly, an employer must have a fair reason — which the law recognises as including capability, conduct, redundancy, statutory restriction, or some other substantial reason — and must have followed a fair and reasonable procedure in reaching and implementing that decision. Both the reason and the process must be fair.
The qualifying period for unfair dismissal protection is set by law and may change, so the current threshold should be confirmed rather than assumed. Certain dismissals — such as those related to whistleblowing, pregnancy, or trade union activity — are automatically unfair from day one. Our guide to unfair dismissal for UK employers covers what fair dismissal looks like and how to manage the process correctly.
