Notice Period and Leave Sanctioning
The notice period is intended for finding a replacement and ensuring the outgoing employee completes pending tasks. Letters typically do not specify that notice must be given for 30 working days. Generally, the notice period mentions the number of days or months, without specifying working days.
Hence, refusal to sanction leave is not legally correct. However, other rules pertaining to leave should be followed. Sanctioning leave is always at the discretion of the manager. The manager cannot reject leave solely because you are on the notice period. They can, however, state that since you need to complete your tasks, leave is not sanctioned. Legally, rejection based solely on the notice period is not correct. However, rules pertaining to the general sanction of leave can be imposed.
