Another solution might be UNIONS that would have __membership verification__ including things like citizenship (which country(ies) are they a citizen of?), skills tests and training, etc.
Just like competition requires 5+ similarly sized entities for a healthy marketplace of companies, my informal opinion is that unions probably similarly shouldn't have overwhelming market share. However my feeling on contracts between unions and corporations is that the contract should be negotiated between multiple companies and multiple unions to produce the most level playing field possible.
