At what threshold do collective redundancies apply?

Where the numbers set by law according to the size of the workplace are exceeded within a one-month period, the collective dismissal procedure (notifications, waiting periods) applies. We plan the restructuring to comply with that procedure and to reduce the litigation risk. The thresholds themselves are fixed by Article 29 of the Labour Law: within any one-month period, dismissing at least 10 workers at a workplace employing 20 to 100, at least 10% where it employs 101 to 300, or at least 30 where it employs 301 or more, counts as a collective redundancy. The employer has to notify the workplace union representatives, the relevant regional directorate and İŞKUR in writing at least 30 days beforehand.
