Isn't 16 minimum age? If you can get hired at 15 and you can keep up your studies, go for it. You may find it a good reference for later work AND you just might find working at Mickey D's a good reason to continue your education at the college level.
No, you can't do the job at Mcdonald's because you are just 15 Could I ask you one thing; why do you want to do the job?? At this age, you must prefer to do the study and after completing your
college, I would suggest you to do a good job. Best of luck of your future.
