People comparing this with slaveryi, seriously? Sheesh! This is undoubtedly a very demanding job with an exceptionally strict environment. But the salaries are high to compensate for that.

Running an offshore oil rig, working in a cruise ship, or driving a truck on Alaska's Dalton highway are jobs that require strict discipline too. There are millions of other jobs like this.

You have a choice. Don't like it, don't work there. You signed a contract fully knowing the rules. Resign!
