Pros
Depends on department and managers. You answer to several people, Office Space style. Sometimes work is pleasant and manageable.
Kontras
Some mangers are actively trying to push you out. Experienced great deal of sexism from direct management. I was doing the job of a employee who left with a job title much higher then mine, but I wasn't promoted or even given a raise. Just given more work that kept adding up without adequate training. Key people leaving leaves big holes, but no replacements, so you are asked to step up without any knowledge of the project left behind halfway finished. My regards for safety were answered, but was punished for bringing it up. Basically I was super frustrated before leaving. Weekends are mandatory and you are always on call, no matter what. No compensation for hours worked past the normal 8-5 as a salaried employee. Spent 12 hours at work Tuesday, better be in at 8 or earlier on Wednesday.
