Pros
If you work hard and are a good employee you will keep a job. The company provides benefits at reduced cost to part time supervisors. Pay rate is decent for part time management positions so long as you do not have a college degree. Work day is fairly predictable although there can be drastic swings in responsibility at any given moment. Lots of eyes on your work at all times for better or worse. Safety is important to the company. Some of my frustrations may be local as other centers might be better managed from the top down or situations might be different.
Cons
Seemingly not much upward potential within the company at this time. The pay rate it mediocre if not sub par if you have a college degree and work in part time management. Dealing with union workers and stewards is a huge PITA at crucial times. The union is more interested in keeping and adding jobs than maintaining an exceptional workforce. Full time management leaves part time management to run operations while they handle drivers for the most part. Prepare to be inundated with paperwork and reports. Company is all about the bottom line for sure, yet they pay out the nose for labor in some circumstances.
