Pros
Relaxed, blue collar environment where (depending on your department) you can leave work behind when you walk out of the door each day.
Cons
Department success within a branch is often defined by the department type - some are more likely to be profitable than others based on the nature of work performed and associated profit margins. However, different departments receive different perks based on overall success that is largely out of control by those working within it. Systems are out-of-date, complicated to use and poorly invested in. You're paid what you ask for, so do your research or you'll end up paid significantly less than similarly titled and experienced colleagues with no way to catch back up. Bonus compensation is at the will of your branch manager, meaning you may get more... but you may also get less. Mistakes are not corrected for an entire quarter, which means it could be 6+ months waiting on incentive compensation pay.
