Pros
i work as a Part-Time Sup out of the Seattle Hub. I'd say how long i've worked there, but it would single me out as turn-over for even my level of management is not far off from part-time hourlys. We are expected to work somewhere in the neighborhood of 25 to 27.5 hours per week. Anything above that is an hourly calulation based on your monthly salary, it comes out to be straight time if one were paid hourly. Bonuses were taken away as of this year and spread out as weekly pay. As a PT sup, we also get tuition assistance. It comes out to $4k per year which is $1k more than PT hourly. Promotions are possible and no longer require a 4 year degree within management.
Cons
A lot of stress comes with being a manager of UPS. The union is very unforgiving when it comes to grievences. Upper management typically has horrible plans for increasing production or decreasing labor. Upper management rarely seeks advice from hourlys or lower management staff on best practices. The technology used (aside from bluetooth scanners) is laughable. I often have to use a 15 year old computer with an even older 3rd party software to complete some of my tasks. To reboot the program takes half an hour minimum. it doesn't make sense when I could go to a garage sale and pick up a new(er) computer that would run over 3x as fast for less than the cost of a grievence.
