Can I favorite a worker?

Yes, you can favorite workers to easily rehire them.

As long as you have paid a worker for completing a Shift Gig, you can favorite them. 

You can do this by:

• Going to the Worker Groups management screen (you get here by expanding the Worker Groups section of your Profile), expanding your Favorited Workers and searching for them by name.
• Adding them to your Favorited Workers from the Rate & Review screen at the completion of their next Shift.
