Pros
People on Nights are laid back in demeanor, making conversation and requesting assistance easy. Folks also frequently listened to their phones while working. Depending on specific start times, you can avoid rush hour traffic. SECURED, covered parking garage. Decent cafeteria, though I never used due to prices. Standards are usually achievable, and if not, you need only show improvement before the end of 3 consecutive review periods (every pay period-2 weeks). Offered opportunity to work in alternate departments/units occasionally. Also occurs when the unit you're working in is closing down for the season.
Cons
It is late night; you will be working until 12 am or later. Standards can become extreme, especially for newer employees. Release/Recall numbers (same number, two uses) are somewhat more heavily influenced by years of service than actual performance. This puts newer hires at a distinct disadvantage regarding when they are "released" from duty. Release/Recall numbers also influence who can even be offered an opportunity to work in another department. You have to hope that some more senior persons elect to leave the season at earliest opportunity. Dusty environment; would advise bring some alcohol wipes or some other cleaner for your desk, as it is likely shared with a Day Shift employee.
