Eternity. I doubt even with all time forever you'd be able to do everything. Our world is ever-changing, much less the wider universe.
The one stipulation I'd put on living forever is the ability to change with the universe. Who's to say physics will even allow us to perceive reality in a few billion years, if we're stuck the way we are?
I mean... the PO shouldn't have come in at 5:01 if they wanted it approved that day. That's just rude.
I work in document control, so I'm sending documents between companies regularly. Often, at the end of the week someone will dump a 100+ document transmittal on us half an hour before the end of the day. And then they go home.
I mean... you didn't say anything else, how else could you have meant it? You even complained that them leaving on time was inconvenient when someone else dumped something in their desk after working hours.
That is 100% not how you framed your initial comment. It was very much focused on how the workers weren't going above and beyond to work when they didn't have to.
Sounds to me like they were reacting to a shit situation in the most appropriate way they could.
