To request a leave in English, you can write or say something like:
1. “I would like to request a leave of absence from work/school from [start date] to [end date] due to [reason for leave].”
2. “I regret to inform you that I am unable to come to work/school due to [reason for leave] and would like to request a leave starting from [start
date] until [end date].”
3. “I need to take a leave of absence starting from [start date] to [end date] due to [reason for leave]. Please let me know if this is possible.”
Remember
to provide a valid reason and to be professional and polite in your request. It is also important to check your company/school policy regarding leaves and to follow the proper procedure.
