How much notice of proposed redundancy must be given to employees?

This depends on how many people you are proposing to dismiss.

• Fewer than 20 dismissals: it is obviously courteous to give as much notice as you can, and to observe notice provisions in your employees’ contracts.
• Between 20 and 99 dismissals: consultation must start a minimum of 30 days prior to the first dismissal.
• 100 or more dismissals: consultation must start a minimum of 45 days prior to the first dismissal.

Remember, when making collective redundancies, you are under statutory duty to consult and inform employee representatives about the proposals.
