I can't imagine what would cause a person to act like that, and on his last day/week of work! Some kind of psycopathy?
Yeah I am manager. I am pretty honest with my employees. One of my normal sayings is "you have to look out for #1 " (#1 = yourself its not a Star Trek reference) That said i never say things like that on comms. And usually preclude them with things like "this conversation never happened" etc. But i feel like part of my job is to give them career and life advancement advice and if that means leaving my team...so be it…
Hopefully there aren't too many orgs left out there where a manager would be having to do this off-the-record; certainly it feels like the orthodoxy for some time has been that workers do their best work when they're well-rested and have had breaks, and at a systems level, people being away is important for identifying bus number issues.
All that aside, my company's accountants get antsy about what overhanging PTO does to the balance sheet, so there's a very explicit top-down mandate around fiscal year end time to get people using up their vacations.
