I come down in the middle. I think that some companies should be encouraged to be founded with a commitment to workers and as an added benefit, should have "cause" policy for firing people. The reason I don't think all employers should be forced to have it is that they just will make things up. As it is now, they MAKE up reasons to fire you. Even now. If this was forced upon them they would take less chances on "questionable" people and they would simply increase their harassment of you in order to trump up reasons to fire you.

I would go further and say if you really want this to stop the real reason this is happening is too many people applying for jobs. You should make sure that you do not support HB1 Visa holders or any sort of guest worker program, immigrants, and anything that could change the market forces that keep companies in check. Right now companies can abuse these systems because they can ship in cheap labor from other companies and literally these people will have to leave the country if they get fired.

In the 80s there wasn't enough employees and I had retail stores begging me to work for them and giving me bonuses. Force out 1/2 of these cheap labor sources and employers won't be so quick to fire.
