Pros
Consistent schedule, no changes. I worked in Reeb Finish. They'll tell you the review raises are only $.50 but you can get more if you work hard. My first 90 day review raise was a $1.50. Consistent/contractual reviews and raises. Standardized vacation/personal days.
Cons
No accountability, uneven workload. They would hire people I wouldn't trust to hold a screw driver let alone use pneumatic tools. People would disappear to the bath for 15 minutes of every hour. Everyone there does the minimum and it becomes contagious. I have too much work ethic to do the same but was eventually punished for it by running my area. I was given all the responsibility with no authority. I couldn't take my vacation days because they said no one could fill in for me. Would have lost them if I hadn't left. I had two "partners". One was given to me only because he got kicked out of his department for not speaking English. The second hated his previous position so faked an injury to get switched to mine. I brought my concerns to the supervisor several times and his favorite reply was "I'll see what I can do" so I'd leave him alone. He was too afraid of being the bad guy to make obvious changes.
