> "sunset my bus factor"

Completely OT: I absolutely know what you mean, but ugh, corporate jargon.

Personally I find "bus factor" to be one of the less egregious pieces of corporate jargon. It's a problem that mainly hurts the rank and file and is utterly irrelevant/invisible to management until it becomes very visible and we inevitably take the blame and eat the consequences. Learning to speak their language to communicate a very real problem is a key deliverable.

I do feel a bit ashamed of unironically using "sunset", although in my case it was more in the sense of "ride off into the ~". It was my last corp job (hopefully) ever.

Returning to add: the benefit to employers of acting like their (ex-)employees are human is that we finished off with a very friendly "if you're interested in coming back, the door is always open", and indeed during my time there I had more than one ex-colleague who became a colleague again. Often at a much higher level and salary bracket, tech promo being equally broken everywhere.
