If you believe the legal protections in place as a direct result of the labour movement (of which Unions are just one part) will remain in place in the face of constant well funded opposition by Capital then I have a case study for you in the UK, we call them Zero Hours Contracts.

Another UK example, you effectively have very limited rights until you’ve worked for a company for 2 years. Before then they can fire you for any reason they care to.

Zero hours contracts were never banned in the UK and in fact have been restricted over the years and debate is still ongoing on whether to ban them altogether.

We have diverged significantly from my original point...
