No, you're wrong. If everybody quit cooperating in this thievery, the employer would have to change his ways or he wouldn't be able to find installers to hire.
You are right, but you are missing one very important part, the first ones which stop "cooperating" will need to look for new job.
If "everybody" jumps when something wrong in the world is happening the world will be better place, right?
Why it isn't ?
