Pros
The pay and benefits are good. Promotions are steady for the first couple of years. Plenty of overtime is available.
Cons
Work/ life balance is non-existent. Weekend, holiday and late-night work is required. Most of the management does not have lab experience. Many co-workers are only there for a "starter job" and don't care about the job. Don't expect to get anything from their recognition program. That is only for the people that complain about doing their job, not the people that actually go above and beyond. This year, annual merit increases were reduced to under 1%. If you stay in one hourly position for too long (1.5-2 years), you will get "stuck" there. In order to move up to a salary position, you will have to take a pay cut.
