Pros
Maybe benefits for full time employees? The discounts are a joke. If you move beyond package handling there is advancement opportunities. 90% of the package handling managers are barely old enough to buy a beer...so it's a good place to start getting management experience. Opportunities come up often because noone wants to stay in that role for any length of time.
Kontras
You are a number, not a person, not an asset, nothing. You are replaceable, and they have no problem telling you that. even though they can't hire enough people. If you last more than a month, you are a veteran, and even then they give no care about you. Half the equipment is broken and dangerous, but dont get hurt because thats too much paperwork for admin. Dont you dare use the bathroom if it's not a scheduled break. They will tell you to stay hydrated but give you the stink eye if you stop moving boxes. During the winter half the water fountains froze and it took months to fix. Employees are treated like criminals. Can't bring cell phone in or listen to music but admin can play on their cell phones all day long. Don't get sick, they won't believe you. Training is a joke. They tell you 90% of people hired don't last a month. Almost once a week the safety message includes some sort of threat about firing you. Also no diversity in leadership... the board of directors is a bunch of old white dudes.... as ancient as their management philosophy.
