They send a scare letter, but will not pursue. The cost to just step in a courtroom is 25,000. Most judges side against companies in these matters unless the company offers a severance package to the employee.
They sent me 2. So glad I'm out of that idiotic industry. Who the F cares what this stupid company has?
You will get 1-2 threatening letters but unlikely anything will happen. Cost and public perception usually prevent companies from pursuing these in earnest.
