Update:
IG got back to me on the status update.
He and the Union spoke to the individual. They informed them of the issues and came up with a remedy. Supervisor is working together to enforce this remedy.
Hopefully, this is a great move forward and they don’t relapse into that same behavior.
Coworker works just fine, really productive individual. They just stink. Well, did stink… They didn’t show up today, hopefully they are better starting tomorrow, at least, at the job.
