HR department works very long hours, usually till 9pm is the norm. Peak period can mean just two hours of sleep and working 7/24. No time off, no OT pay because the boss said this is part of work. Expect phone calls from office between 7.30pm to 9pm on a daily basis and boss like to ask "can you amend now", "you not in office then is your notebook with you?" Too busy for your family, too bad. You end up wondering why you are there and if possible will end up leaving. Phone calls and text messages from boss on weekends and PH is very common.
