I'm not working today but what this brings to mind is a recently hired coworker who apparently is.
My small team has had a nice culture of keeping our work chat mostly confined to our normal working hours, except when some issue comes up that needs attention. This new coworker has lately been shattering that. This person not only posts in the evenings, weekends, and sometimes into the graveyard shift, but does so in a cloying, overeager, performative kind of way.
"while that job was running I took the opportunity to go learn this new skill!"
"I finished this step of the process. Now I'm gonna go do the next one!"
...and updates on what they're doing and their reachability, at all hours.
"I'm going to have dinner because I haven't eaten anything today, but I will have my work computer and work phone with me so feel free to ping me".
Even today, on Christmas morning, there was more from this person in slack, posted after midnight on Christmas Eve.
I do my best to push it out of my mind, but I can't deny this adds a layer of stress for me. I don't want work conversations to stretch into nonworking hours. I don't want this to become part of the culture in my team or company. I don't want to see this kind of behavior become the expectation. I hope nobody ever asks anyone else to be more like this.
