until you graduate though, you may not be able to work much jobs. food service, grocery, retail, movie theaters, are probably all you can do.
when you do graduate though, a lot more can open up. warehouse, logistics, customer service, inside sales, business development rep, appointment setters, administrative assistant, etc. a lot of companies have those positions for entry level and may not need college degrees. if you're graduating in the spring, start applying in the winter time. you can put your intention date to graduate, and hopefully get a start date soon after. lots of people do that.
talk with a teacher or counselor for more help and advice. they should have resources too.
the military is of course another option. contrary to popular belief, they have hundreds of jobs that aren't all combat or infantry related. plenty can find similar careers when your service is over. enlisted personnel jobs are most four year contracts. some require six years though. do some research and look around online.
some high schools have job fairs for older students. again, ask a counselor. and businesses from all over can come and you can apply right there and potentially interview for jobs. military recruiters may also attend depending on the location.
