 If the number is under 100, but over 20, then the employer must begin consultations 30 days before.There is no duty for collective consultation if the number of redundancies would be under 20 people, though an employer will still be bound by provisions in the employees' individual contracts, and the duty to give reasonable notice in ERA 1996 section 86.If redundancies are unforeseeable, when consultation could not be reasonably done in time, then section 188(7) absolves the employer of the need to pay compensation.
