Work from Home permission under SEZ rules: formal WFH schemes required, approved if unresponded within prescribed period. Implementation of Rule 43A requires units to adopt a formal WFH Scheme and notify the Development Commissioner at least fifteen days before implementation, submitting a covering note with employee counts, categories eligible for WFH, duration (up to one year per application), an undertaking to ensure physical attendance consistent with approved percentages, and details of employees when WFH covers half or more of the workforce. An accompanying spreadsheet must list eligible employees, identification details, asset assignments, and individualized WFH durations. Applications are processed within fifteen days and are deemed approved if no response is received.
