But really, I’ve been in a similar circumstance before though not for such a long period.
I’d shadow others, study/research documentation, contribute where I could.
I also prepped for a project management certification along with other professional credentials. Though I got staffed before finishing them.
I get sucked into the BYU football wormhole and create stupidly detailed spreadsheets about what Tom Holmoe should do in terms of conference realignment.
And if it lasts too long I job hunt. He hasn’t been here long enough to do that, but he might be tempted if it goes too much longer.
