No one get surprise by seeing this ! Overtime is a very common "used" word in Software Industry.
Up to many extend, one's appraisal and future is dependent to this overtime. I don't know why, but all the senior person want his/her subordinates to do overtime. It's like someone greatest appreciation "I had worked till 12.00 PM yesterday"
Life is simple, but we want it to be more complex. Frankly speaking if I decide to finish the work before 6.00 PM, I do it in any cost except that your day is bad or some mishappening occurs with you, your work.
This trend originates from US, UK client where the daytime is 360 degree to ours, and so for maintenance or online support project you have to be available there at night. But trend converted into craze and craze converted into habit.
How come we forget that God created us as human. Health, family relationship is something for us.
Just think that "Is it necessary to stay their in office, Is someone is not waiting for you their in home, Is not you love to see sunset and sunrise ?"
