They don’t do that to me because I’m a contractor who they me more than I need them. However…

I’ve seen this exact thing play out several different ways. My favorite recurring one: “Why didn’t you respond on slack/why were you offline?” (Always over some bullshit that could wait or that someone else could have handled).

“I worked the maintenance window last night because you said this non production change couldn’t be done during the day”

“Well you should still be monitoring in case there’s an emergency!”
