Depends where you work - Assistant Manager The UPS Store Employee Review

Promotion worthy if you are diligent. Great potential

Large amount of skills required to learn

Due to understaffing, certain staff gets more hours. Decent enough pay compared to other companies, if you're patient enough (several years later) you can finally move up. You'll do decently if you're put under a decent manager.

Always understaffed and managers say we are "overstaffed", managers can influence raises to some degree by what they say and their employee biases, etc.
