Hi,
No bank employee can be forced to work after the scheduled hours.
If you are asked to work for extra hours , you have the right to question that. The demand is not based on any rule or norms, it is purely on his demand and whims.
Hope that you are given an appointment letter which shows the work timings.What does it say.
actually no difference between male and female employee as the hours of work are during day not in night. So make objections about it and what about the other staff are they also leaving late. In case your boss does not agree take this matter to higher authorities.
