Through Upgig, you are able to get gigs from many different companies.
Each gig has it's own separate employer. It can be the client itself or through a 3rd party employer assigned by the client.
Upgig is never the employer.
Before you can receive/accept an assignment in the app, you must sign an employment agreement with the relevant employer for the gig.
You need to sign a digital employment contract which you can then see in the app.
