Pros
Currently have the flexibility of working from home with "return to the office" based on personal comfort with that (but that is not the case for employees in other parts of the country). Customer interaction is generally positive, except for the instances where I'm held responsible for something completely out of my control.
Cons
The internal red tape and corporate gas lighting is a lot sometimes. The corporation is going through a "transformation" that has made folks wonder about their future at UPS, and question their loyalty over the years (jobs are being cut with little fanfare). The "transformation" also makes it clear that our real customers are stockholders, not shippers. As with many corporations, decisions are made by executives who don't have to use their own services and haven't had boots on the ground in years and are out of touch with the reality of the day-to-day of most of their employees. Internal mobility is limited, and employees who express interest in moving to other departments are sometimes "blacklisted" in their current department. Salaries in some departments are some of the lowest across the industry, which is supposed to be countered with other "perks" (like the management incentive program) but it often doesn't pan out that way.
