Propak is the best paying shop around, however one mistake in your first three months they boot you. No feedback or consultation just out the door without knowing what you even did, could be a safety infraction, or just a rough night with poor quality or production, you won't really know and there's no second chances.
The culture is very "Clique-y" with settled people not really showing new people any respect, Infact quite the opposite, and that includes management. No feedback from supervisors. High safety standards.... sometimes. It has a reputation for being a revolving door for a reason. If you're a contractor stay far far away, they have a reputation for having bad experiences with contractors (especially rig welding contractors). If you gotta take it as a contractor make sure you submit a detailed inventory of all your personal tools that you're bringing on site, and get it signed by upper management, otherwise you might not be leaving with then at the end of the job.
Safety theater, clique-y, culture, hard to balance social life, very unforgiving.
