I expect that he works at my father's deli until he finds other work
Why would he do that?
Because I heard that you can work there till you find other jobs.
It is hard getting jobs sometimes so it is good to at least earn some money at a temporary job while trying to get another job that is more suitable. It will help pay the bills until you can find something better.
Thank you, I never knew the options.
Of course, I am here to help. It is always better to work at a job until you find another one instead of quitting and then starting your search.
