The FTC decision has already been halted by a Texas court nationwide. It's probably going to make it's way to the Supreme Court eventually, but given the courts recent rulings I suspect the FTC rule won't survive.
> Nearly one in five workers in the United States are bound by a noncompete agreement preventing them from finding a new job or starting a business in their field when they leave their employer. Noncompetes are currently governed at the state level, and as a growing body of research shows that noncompetes suppress wages, reduce job mobility, and stifle innovation, states are moving rapidly to restrict them. Currently, four states ban the use of noncompetes entirely and 33 states plus DC restrict their use.
