cant we call it slavery when someone impose rules on us and we have to follow those rules whether it is a company's manager or prime minister or judge or husband in some cases a wife do :)

If manager says you have to be present at 7.00 o' clock otherwise 500QR cut :( means you have to be present. Its a kind of slavery where you have no choice. You may look for other job but still you will get the rules to follow.
