"I mean, people do sometimes change jobs, that's among the reasons why hospitals have two people with each emergency cert. You'd leave a larger hole than usual, but we'd pay higher than usual temporary bonuses for picking up certs, and be back in compliance a couple of months later."
Another note of that sting from Catchall's criticism. People whose departures would leave large expensive holes in your organization are usually people you want to pay more, above and beyond linear payments in labor or numbers of certs; and maybe someone should've noticed that fact about Merrin, what with the general heuristic being a proverb.
