It was interpreted by the “hi” folks as me not ever being at work.
Eventually (as I anticipated) someone complained that I missed an important priority issue about X.
I had to explain how “hi” /= important issue about X and that I revive so many “hi” messages that I couldn’t assume they’re all important.
It was pretty tiresome explaining it, but it worked, I stopped getting “hi” and got “hi, important issue X”.
