Vacation Period and Notice Requirements
Vacation period refers to your eligible holidays, and the purpose of notice is to ensure that the employer has sufficient time to find a suitable candidate for your position. By serving notice, you have fulfilled your duty, and the college management can easily find a replacement before the college reopens. It is the employer's responsibility to grant you vacation time or holidays. Requiring you to work during your vacation does not benefit the management in any way.
The standard rule that employees cannot take leave during the notice period does not apply in this situation. Even in such cases, the employer cannot compel the employee to work on Sundays and other holidays that occur during the notice period. Your vacation time is akin to holidays, so the employer's refusal to grant you vacation time is not legally permissible.
