Pros
Nice benefits. They don't outway the bullying and harassment from supervisors and managers. Administration is removed from connections on the floor. This disconnect allows bullying.
Cons
So many to discuss. HR does not remedy complaints that come from the plant workers. They listen and don't make changes. Managers are unmonitored and allowed to oppress workers and prevent progression in advancements if they don't like you. Line leads are not monitored and tend to gang up on an employee that doesn't fit in. Training is considered a 'gift' or reward for an employee. If you are not liked you are not trained. Bullying and viscious competition is not reeled in. HR knows of these things and does react to change these situations. High turn over is because of these issues.
