I'm not saying a bunch of pilots should do this or that. I'm saying one pilot should not work if he feels he is fatigued. Perhaps then he should go to the doctor and let him know so some time off can prescribed to get his body back in shape.
If the company does not like it then they can stuff it. The pilots life and his family's well being are the number one concern.
If that is not acceptable, then it is time to change companies or get into another line of work. Flying hundreds of people around the world while you believe you are fatigued is not only irresponsible, it is bordering on criminal.
