When I worked Ina warehouse/yard we’d regularly need to text each other in our off hours for very simple “hey where did you put x” or similar because management couldn’t be fucked to help us organize efficiently
I’ll help out a fellow wage slave if me taking 15s to reply would save them a few minutes of hassle
But I’ve only ever done that at non-corporate places where I actually like the co-workers on my pay level, the corporate jobs provided communication software and that shit was programmed to be muted the minute I was off automatically
