What is the consensus on pilots not picking up any open time unless they are getting 300% for it?

Sorry…I didn’t put the question mark in there.

Essentially, could we get everyone to agree to calling crew support and asking for 300%, and walk away unless they give it to us? I see a lot of open time getting picked up at 150% and at most 200%. I think we should start collectively forcing the hand that feeds us to feed us more food if they want us to stick around.
