You are completely failing to see my point--if gig company A had to employ your Dad as a part time or full time employee with guaranteed minimum wage or work hours and other benefits he wouldn't have to tetris together an insane set of gig work jobs to keep from being evicted or starved.
Your dad is forced to be an indentured servant for these companies that can't make money without exploiting people like him. And somehow you are immediately going to bat for these employers... pretty sick IMHO.
