Ideally, you would find another job first. Then ask your employer for a raise appropriate for you working 7 days a week if you are on salary or ask for appropriate overtime pay if you are paid hourly. If your employer agrees and you like this job, stay and try to help them out. Otherwise, leave and start your new job.
