Retrenchment application notice requirements govern electronic filing, worker service, and conspicuous display at the establishment. An employer intending retrenchment must file an application in Form XIV with the Central Government electronically, stating the reasons for the intended retrenchment. A copy must be sent to the concerned workers electronically, in person, or by speed post, and the application must also be displayed conspicuously on a notice board or electronic board at the main entrance of the industrial establishment.
