Dear,
In my point of view, an employer can force their employees to avail Compulsory Earned Leave only on the following terms and conditions. It should be linked with your LTA scheme (Leave Travel Assistance plan). It should be only once a year. For the same, employees will get a sum amount as Travel Advance or reimbursements. Other than the above reason, the employer has no right to cut the earned leave for any reason whatsoever. If your HR Manual states any specific reason for the same, please share it with us so our seniors can guide you with more appropriate suggestions.
