Collective redundancy refers to a situation in which an employer, based on the average statistical workforce for the preceding six-month period, intends to terminate the employment relationship according to the following criteria:

• at least 10 workers, when employing more than 20 and fewer than 100 employees;
• 10% of the employees, when employing between 100 and 299 employees; and
• at least 30 workers, when employing 300 or more employees

within a period of 30 days, for reasons in connection with its operations (such as, for instance, a reorganisation, a layoff, or a termination of an organisational unit).
