Dear Fariza Haque Labony,
Employee Marriage Leave During Probation
Usually, when an employee joins a new organization and their marriage is scheduled during their probation period, the new employee has to disclose or share this information with the panel members at the time of the interview. In many companies, the new employee is given advanced PL (Privilege Leave) or EL (Earned Leave) as a special case. I have hardly seen any company granting LWP (Leave Without Pay) to any new employee for their marriage. Again, I would say it depends on the leave policies of each company.
Yes, I agree. If the policy does not cover it and if it is mentioned in the appointment letter, then this is the policy. But it's better to ask for permission than to fight during probation or for your career. I would suggest letting him submit an application to the authority mentioning the valid reason.
Tips for Handling Leave Requests
A tip for these types of problems: Please formally invite your management and top boss and ask for best wishes in such matters. Ethically, they can't deduct but can accept your leave.
Regards,
Tofaael
