>do you think lawyers work on Jira tickets?

Yes, I more or less think they do. Unless they are a headliner or founder of their own firm.

Lets say you are a lawyer at glob corp, and they get sued. Do you really think you can say "Eh, the other guy has a point. I am not going to defend this one."? You either work the case defending glob corp, or you are no longer glob corp's lawyer.
