Pros
Money if you can negotiate, If you can't, then this is also a con.
Cons
Management goes out of their way to make the employees feel replaceable. Management actively tries to pit employees against each other. Management will fire someone for clocking in too early, but will keep a person reported to HR for touching people, then actively punishing the people he thinks reported him in the first place. Lazy engineers that refuse to do their job, but will be more than happy to take a 3 hour lunch off site, usually when the techs are begging for help. Decisions affecting maintenance are always done by people that have never picked up a wrench, much less seen the inside of the tools. HR is never around and when they finally get to you, you are treated as the criminal. If you ask for a shift change, management will write you up for a bogus violation and prevent your shift move because of the violation.
