I did contract work, the management of the contract team had an unreasonable expectation of people under him. He wasn't married nor had kids, so he expected everyone to work 24/7. I was even threatened of being fired when I had to leave to take my son from school to the ER due to an accident on an icy day. It's been years, I am not even sure the Contracted company works under BP anymore.
Great team to work with everyone looks after eachother. It's hard work but rewarding even if it is just the five minutes you give to the old boy who probably only talks to a handful of people. I find the management team very flexible and helpful always willing to listen if you have any issues. If you put the hard work in you are rewarded for it with progression in the company.
