Currently the management is the main issue. I suspect that will change soon. The current system is to promote friends and family, and ignore the employees with over 18 years experience. There is a major divide between management and hourly employees, with supervisors stuck in the middle.
As far as the work, there is not a single hard task there. The work is straight forward and simple, its just hot for production employees. Its a foundry style environment, so if heat is a problem do not apply. If you work hard, no matter how others around you slack, it will be noticed. Not necessarily rewarded, but they know. The pay for the work is good. The problem is that in two years, you're done. No more raises outside of cost of living. The guy that's been there eight years, will make what a three year guy makes.
the pay is on point for the work
lacks solid upper management
