you serve only your boss and the company,slog 9-10 hrs affecting your heart,brain etc,have to look for excuses to take a leave to attend some marriage function,go for a picnic/shopping/meal with your dear ones,sometimes have to work on holidays also as overtime,if company is going in losses,tolerate politics by colleagues,have to drive/travel by cutting your way to traffic jams etc
many marriages also break since u had no time for your spouse and kids,and many companies expect u to work on Sat. also..so u get just 1 sunday off after toiling 6 days a week.9-12 hrs. daily
u may/may not be paid well,yet u have to be perfect.
lastly the risk of losing it.....
aren't current jobs modern day slavery/bonded labour?
i am not saying that one shud not work.....but the above conditions that are rigidly imposed on employees make me believe so..
