If management doesn't beat you into the ground, don't worry. The regulars will do it for them.
Pros
Pay, don't have any other pros but I needed five words
Cons
Backstabbers; office politics; dangerous buildings filled with lead paint, asbestos, and mold; longgg hours; poor benefits (health insurance is unaffordable, no sick leave for subs, can't use annual and even if you could, it adds up so slowly that by the time you reach your unpaid mandatory break you'll need it to cover that, uniforms are hand-me-downs from others and filthy, getting new ones from management is like pulling teeth); dangerous conditions since you're not in neighborhoods when the regulars are more dogs will be out than when they deliver, angrier customers because you're not "on time"; management will assign you multiple routes but when you get injured it's your fault for not being safe; vehicles that give out noxious fumes and have no AC in summer and often no heat or defrost in winter, brakes give out frequently and I've even seen first-hand a time when I took out the key and the engine was still on...... I could keep going but I think you get the picture. RUN.
