I work on Covid at my local public health department. Yes, someone can still test positive weeks (or even months) after their initial infection. It has to do with the tests still picking up "debris" from the Covid infection, even after the initial infection has been dealt with (I don't know all the science, but that's the gist).
According to the CDC, people can leave Isolation 10 days after either 1) symptom onset or 2) a positive test (for those who never had symptoms), assuming they've been fever free for at least 24 hours and symptoms are getting better.
In my county here in California, we really discourage negative testing for returning to work. It puts a strain on testing resources, and can force people out of work for much longer than needed. I don't know what Equity or individual theaters are following - despite the above CDC guidance, I occasionally hear of employers who insist on getting a negative test, which is truly a pain in the neck for everyone involved.
