Mass redundancy: consultation comes first
If 20 or more jobs are cut, the employer must consult in advance — at least 30 or 45 days. We explain the rule, the periods and what happens if it is breached.
Thanks for £1
Mass redundancies are not the employer's decision alone. If 20 or more jobs are at risk, the law requires collective consultation first. This is set out in section 188 of the Trade Union and Labour Relations (Consolidation) Act 1992.
When the rule applies
If an employer proposes to make 20 or more employees redundant at one establishment within 90 days or less, it must consult the appropriate representatives — a union or elected employee representatives.
Minimum periods
- at least 30 days before the first dismissal — for 20 to 99 redundancies;
- at least 45 days — for 100 or more.
Consultation must start in good time and finish before the first dismissal takes effect.
What must be discussed
How to avoid redundancies or reduce the numbers, and how to soften the impact. The employer must give information in writing: the reasons, the numbers and categories of staff, and the selection method.
If the rules are broken
Employees can claim compensation (a protective award) at an employment tribunal. Individual rights — protection from unfair dismissal and redundancy pay — apply separately.
Note: the collective-redundancy rules are being updated in 2026; check the current thresholds at the time of any redundancy.
