> Companies should also be legally barred from hiring for three years if they engage in layoffs.

I like this. I was trying to think of some way to allow layoffs for struggling companies but not reward layoffs for companies that are making a profit, who just want to make more. My idea was more around the executive team being unable to take a salary or having to fire the CEO or something, nothing which as I worked through in my head seemed workable.

In some places, if an employee is made redundant the employer is barred from filling the same position for a period of time.

Enforceability is a problem; it's always been trivial to re-write a job description.
