They do not care what other job you have or your scheduling for either job. They want you in or they’ll right you out just as fast. Most coworkers are nice and most managers are supportive. If you can handle some tense energys and the fast paces environment then your good. Plus side they have good benefits if you work long enough.
When i come into work at FedEx i open all my web pages to start my shipments for them to get cleared through U.S customs. Working in a supportive environment is the best part of my day because questions aren’t a problem.
