Earlier quoted context omitted.
Shotwell literally wrote an email telling them they had to stop discussing the issue or she would consider it insubordination then fired them the next day. No need for HR to do anything when the person in charge is incriminating themselves.
I mean, in many cases that’s grounds for dismissal and legitimately the job of a manager. “Yo, stop bringing politics to work, your job is to make flight controls - not criticize the owners of the company outside of work. You’re being disruptive - stop.” Idk, Musks behavior is what it is, idk why these employees thought it was their role within the company to continue to speak out.
And of course some higher up dismissing it and telling them to stop complaining just makes it worse.
