Credit card negotiation department doesn't go to work on weekends, because banks don't go to work on weekends and holidays, and the working hours of banks are from 8: 30 am to 5: 00 pm. Not only the credit card audit department goes to work on weekdays, but also the financial managers, supervisors and presidents of banks go to work on weekdays and have holidays. Only the staff on duty at the counters and lobby of bank outlets go to work as usual on weekends.
