There is far too much pressure put on every employee. I was doing the job of at least 2 people without being able to come up for air. If you mention that you are under more stress than you can handle, the response is to work harder to get work done quicker. Most of the chemists and engineers are great people, but everyone is far too overworked, which makes for a miserable work experience. Management is only concerned with turning a profit and will gladly replace you with someone who will work longer for less pay.
Forget about a full time job with benefits; they mostly only hire as contractors so they won't need to provide benefits. You are made to feel guilty for taking time off or leaving on time, and most people are suggested to work long hours.
