> I'm going to stay and fight and try to make whatever impact I can. Can you give me some examples of how you would fight? Boss comes in (or whoever more powerful than me, e.g. someone acting on the president's orders), says something with the gist of "Do this, or get fired". What are the next steps that I can take that won't get me fired, but also count as fighting back?
Comply but leak the truth to the media. Comply in a maximally obstructive way. Comply just enough to not get fired but not as much as someone who may be more inclined to please their boss. Enlist other opposition and find ways to multiply your obstructive compliance into other departments. There's tons of "how-to" guides on how to maliciously comply with work demands without getting fired.
These only apply to countries where the judicial system doesn't bend to whoever's in power.
