My question involves a person located in the state of: Calif

A family member is on SSI disability in California. He receives $850 a month to live on. He normally does recycle and other odd jobs to supplement his income just to get by. Someone told him he could file for Pandemic Unemployment for gig work. He did and is supposed to be getting $9500 retroactive.

So how does this work? I am assuming he can not get his SSI and unemployment at the same time. He should report the unemployment benefits and pay back the $850 for 3 months and keep the Unemployment. Will he still keep his Medi-Cal benefits while he is getting the Pandemic Unemployment? Will he need to reapply all over again for SSI when the unemployment runs out>?
