Just to clarify, an example: A boss tells a female employee: "You must have sex with me or you're fired."

Is that coercive?

Depends on what you mean by 'coercive', no?

I'm not sure that libertarians really use the term 'coercion' consistently (as a group, I mean). For some, it is interchangeable with aggression, while for others it might include situations like the one you describe.

Personally, I tend to think that it is *coercion*, but not *aggression*. As a libertarian, I believe that both coercion and aggression are bad and wrong, but that physical force is only justified (legally) for the purpose of stopping aggression.
Luckily, in the case you describe there are many nonviolent ways of preventing/reacting to this problem (deal with these cases beforehand in contract, unionization, boycott, private arbitration, etc.)
