Thanks! If I understand correctly, I should get a one-time official OK in writing before I join, and then I use my own judgment when deciding to do some consulting (to make sure there's no conflicts of interest)? Or do I get an official OK in writing before every gig?

This is what my non-compete clause roughly says:

Duty not to compete: My work at the company requires my undivided attention. I will not, without the company's written consent, engage in any other business that directly competes with the company, uses any of the company's materials, or otherwise conflicts with the company's business interests.
