Pros

The plant had good contracts with opportunities for growth.

Cons

One of the worst plants I’ve ever seen from a safety standpoint. Oil flowed freely out of equipment and the floor sweeper was how they cleaned the oil up instead of fixing the leaks. There was limited to no preventative maintenance done with most equipment run until it was broken. Most of the equipment is 50+ years old and in need of complete rebuild. The maintenance crews were good people but didn’t have the training, tools, parts or support of leadership to do the right things to keep the plant healthy. The Maintenance Manager was an Engineer with limited maintenance experience and his leadership skills were horrid as he constantly trying to force his way with the union with no focus on making the plant safer or more productive. The Maintenance Supervisor was better but unstable so depending on the day he could be spot on or yelling at everyone. Any time anyone brought up a suggestion or exposed his failures as a supervisor, he would lose it and berate the person. Some of the people that worked with the Supervisor for years in other roles said ‘he”s always been like that and HR doesn’t want to do anything about it’. The Production side of the plant was better run but with the old equipment and poor support from the Maintenance Department it was hard for them to meet production requirements.
