Pros
Friendly co-workers, good vacation hours credit, and yearly firm party in Tampa is always fun.
Cons
It's a grind because WC is not very interesting and it's not "real" litigation. The trials don't go to juries, the rules of evidence are simplified (no Daubert), and motion practice is limited. Firm expects a lot of billable hours (because the hourly rate is low) and plays favorites in how cases are assigned and how support staff are allocated. Finally, it appears management and HR have an obsession with watching their employees through cameras and not taking resignations gracefully.
