Do most jobs let some employees work once a week? -

i am searching for a job and i am 15. i have currently not had a job before but i am wondering if i wanted to only work friday evening. do you think i would be allowed? or you have to work a certain number of hours and days every week? do most jobs let some employees work once a week?

You could try Wendy s. I worked there as a teenager and I had a very flexible schedule. Your first week or so you may need to work a few days for training. I am not sure about other jobs but that was the most flexible job I ever had. Maybe other fast food places are like that also.
