I disagree. It is almost as if at work talk on work provided media like slack, should be work related. What is next? People complain about mutiny related chat rooms being banned by the Navy?
Not being allowed to mutiny in the navy is related to the whole violence thing. It’s also the case that people in the navy can’t just quit when they want to. I don’t think you want those kind of rules applying to most workplaces. Talking about pay equity is a good thing to be encouraged.
Ok, then perhaps Apple should ban the channel about fun dogs.
Looking at my company slack, we have a ton of channels with a "soc-" prefix, which we use to designate a channel that's there for social purposes rather than work. I think my employer would have a mutiny on their hands if tomorrow they decided to shut that down.
Plotting mutiny is a crime. Angling for pay equity is legal. The equivalent here would be if Apple broke up a #insider-trading Slack channel where people exchanged Apple’s MNPI.
How much people are paid clearly matches the scope of “... Apple business and must advance the work, deliverables, or mission of Apple departments and teams,”. Paying people fairly advances the Apple teams.
But it's not always work related. My fiance's work has a slack channel called dev-urandom where people can share, among other things, cute puppy pictures. Before covid, my work had a smash bros channel to summon people to play and post new character releases.
That's a strange analogy. The military can compel you, by force, to walk into a hail of bullets. It is not a "job". Though everyone's salary is public knowledge :)
