Make sure you conform and there is nothing different about you compared to the gang already there. You'll be persecuted until you have to quit your job if you are different and the people doing it will tell you that you deserve it. Don't challenge anyone on anything ,you'll be run off. Recognize that almost all 'professional' staff are rejects from other more successful companies and you shouldn't have any problems setting appropriate levels of expectations. Keep your head down and don't make mistakes, other people will grab on to them to make themselves look good at your expense. Oxys 9/80 schedule is really a 9/89 - they will expect you in on your Friday off while making sure they get their bonus hours the other 9 days. It works out at roughly a 9% pay decrease for your hours worked. Don't take an overseas assignment (Oxy have failed everywhere, so that shouldn't be an issue) because you have to work 6 weeks on 1 week off rotation without seeing your family and if you don't like it, they will run you off. Don't expect professional development or support, you are expected to know everything all the time. They aren't wasting money on training and development. If you like persecuting others and helping HR to make your target pay for it, you will fit straight in at Oxy. Other than that, the low pay, no career prospects, track record of fatalities and serious EPA violations and school yard mentality, you should do very well.
