Re-employment of retrenched workers follows seniority-based notice, preference, and vacancy-intimation requirements. Preference for re-employment of retrenched workers is based on seniority and prior notice obligations. The employer must prepare and display a seniority-wise retrenchment list before retrenchment, notify retrenched workers of vacancies by notice board and speed post or e-mail, and give eligible retrenched workers from the preceding year preference over others. Limited vacancy, short-duration vacancy, and non-response exceptions are also provided, along with notice to negotiating unions or trade unions after vacancy intimation.
