I've worked corporate jobs all my life, and I was never one misunderstood message away from being fired. Instead they would've talked to me and, even if they figured it was my fault, they would've given me a warning since it was the first time. No worthwhile employer is firing people for the first offense, corporate or otherwise.

I have worked plenty of corporate jobs; Morgan Stanley, KBC Financial Products, Apple, Synopsys, the intelligence community (not corporate, but just as bad).

Never once was I "one misunderstood message" away from getting canned. I would have quit immediately if that were true. I understand not everyone can quit, but more people can than do.

Nobody deserves to work under that kind lack of of psychological safety, and certainly anyone on Slack and not in a factory has more of a choice.
