Pros
When your shift ends you can relax without worrying about taking your work home with you. It's honest work and when you get good at it, you'll find yourself able to look after others and build leadership skills. If you can manage to make a name for yourself here, you can make it anywhere. Lower/middle management is very friendly and makes an effort to help when they're not drowning in work themselves. 4 day shifts and 3 day weekends is really nice, but you'll probably spend 1 of them just recovering from the intensity of the work week.
Cons
Since I've started here, the workload has only ever increase for operators. Your workload will continue to increase, likely without any meaningful compensation or promotion to sustain your growth in the company. So long as you have the bandwidth you're going to be worked until the very end of the day. Upper management is extremely disconnected from the state of operations and does little to help/show no concern for the well being of their main work force. You're expected to work holidays unless you use your PTO to take them off. The result of all this is of course, a very poor and demeaning culture.
