Rule · TULRCA 1992 s.188
Collective consultation
If an employer proposes to make 20 or more employees redundant at one establishment within 90 days, the duty to consult collectively kicks in. Below 20, only individual consultation is required.
The thresholds
- 20 to 99 redundancies in 90 days: minimum 30 days' consultation
- 100 or more redundancies in 90 days: minimum 45 days' consultation
- Counting unit: per establishment (USDAW v Ethel Austin, ECJ post-2015)
The duty arises when the employer is "proposing" redundancies, which is earlier than the formal at-risk notification. Source: TULRCA 1992 s.188.
Who must be consulted
Recognised trade unions, if any. Otherwise elected employee representatives. The employer must provide statutory information (s.188(4)): numbers, reasons, selection criteria, calculation of redundancy payments, etc. The HR1 form must also be filed with the Insolvency Service.
Protective award for breach
If the employer fails to comply, affected employees can claim a protective award up to 90 days' gross pay (uncapped weekly pay for protective-award purposes, separately from the s.227 redundancy cap). The tribunal sets the period punitively, not compensatorily. ACAS guidance: manage collective redundancies.
