This can be a very stressful job depending on your upper management. I work at one of the busier centers and things are extremely stressful. Fedex is extremely poor at making changes, often times there will be a major procedural change and their way of distributing the information is by posting the new procedure on a bulletin board, due to this most employees are often unaware of what the new/proper policies are.
Fedex's "revenue behaviors" are absolutely ridiculous, they encourage you to sell things that are often times irrelevant to a customer's needs or wants, I understand the need to make a sale (and am good at it) but being forced to offer an unneeded, irrelevant item or services to a customer comes off as disingenuous and said customers are completely aware that you are being forced to sell irrelevant items and are required to use canned phrases in order to sell products.
There isn't much room for growth (although they may tell you differently). I've seen people with little to no experience become managers and shift leads, which results in very bad morale among team members. New hires (all positions) usually get paid more than employees wo have been there for years.
Fedex is doing a horrible job of protecting their employees during the pandemic. Fedex is one of the only businesses I'm aware of that completely refuses to add any sort of physical barrier between the customer and employee (even after numerous requests countrywide sent directly to higher ups) . This is a very customer facing job that often times requires close contact, Fedex's way of trying to "protect" employees is encouraging them to tell customers to keep 6 feet away from them at all times.
