Pros
You get to meet some lovely drivers and they very obviously look for a certain kind of candidate when hiring so you'll probably get along pretty well with your coworkers.
Cons
You'll be forced to work overtime and then have your time card adjusted without your knowledge or consent because "we don't pay overtime here", HQ absolutely refuses to provide more headcount so you're forever understaffed, they've gone through two rounds of layoffs after promising there would be no layoffs, they are actively encouraging travel through a pandemic and refuse to listen to their "essential" employees forced to deal with the backlash first hand while they're sitting in their houses working from home. All while refusing to pay a livable salary to their field employees.
