I am currently working at two different schools under regular contracts. I am up for a third job, but they only do freelance. With the already contracted jobs, I work 4.5 hrs/week at each. One pays 20/hr gross, and the other 15/hr gross. This third job would pay 25/hr gross but under freelance. Is it worth it to work freelance just for 10 hours per week, should I move all the jobs to freelance, or is there a better option?
