Pros
The culture amongst the operators and engineers is good. Some of the lead management team isn't too bad either. Salary is great, considering it's the manufacturing industry and lets face it (the site I work in only produces perfume.. We're not saving any lives here)... However, considering the 12 hour days, pretty much every day, you end up making less than what some make, flipping burgers at McDonald's!
Cons
Unbelievably long hours! Tiring! If you join as an engineer, don't be surprised when you have to clean floors and wipe boards when the big guns come to the site for a visit. You are the lowest of the lowest. And every so often, you'll have to work as an operator for a couple of hours a day. This helps their productivity results. But at the end of the day, you're still expected to have your daily responsibilities done anyway. All it takes is for you to stay at work an extra couple of hours every freaking day!
