FTC bans noncompete clauses
Noncompete clauses are parts of someone's initial employment contract which say that if they ever leave the company, then for a certain amount of time - often one or two years - they're not allowed to get another job at a different company that is considered a competitor in the same industry, nor start their own business in that industry.
Companies that use them say they're necessary to prevent a situation where larger companies can rampantly scalp skilled employees from smaller up-and-coming ones by offering more money, and the time limits are needed to allow any proprietary knowledge an employee has from his time at the company to expire or lose competitive value.
In practice though, non-compete clauses make leaving your job for
any reason impossible because if you've been educated and trained in a particular industry you just...aren't allowed to work in it for up to two years, forcing you into the unskilled labor pool for at least that long and threatening your chances of working in your industry even afterwards since you're not using your skills or getting continuing education to keep up with trends and all that for that whole time.
