Vantaggi
The pay is what it should be for: all the work, danger, responsibility and oversight of other departments. However it is well over 15% compared to other entry level positions in all of the private sector. Also, the pension plan is to look forward to, as almost no one offers this benefit anymore. There is also opportunity to grow as the company is growing and continues to do so. All in all, I would use the words: Job Security, to describe the Pros.
Svantaggi
No flexibility being entry level; you are forced to work wherever (From Rockport to Fitchburg to Providence to Boston to Kingston) and whenever (from 2am to 2am) they need you. This wouldn't be so bad, except; they do not cover your gas unless you are, strictly, on-call and there is no parking for employees. You are at risk of being towed at your own companies facilities. No matter your skills, talent or qualifications you are treated the same as the next guy, I guess you could say that's another down side of a union. However, one would hope that the leadership would do something, anything to make the employees feel appreciated.
