is working with boyfriend a good idea?

sorry i don’t know which group this goes in. me and my boyfriend are 18 and both were looking for a new job and he got hired at a fast food place. he told me i should apply because it’s an easy job, pays 14 an hour to start, and they hire easily. i told him it would be nice but i didn’t think it would be the best idea to work with somebody you’re in a relationship with. i thought this because being around each other that much might get on our nerves if we have the same schedule, which we’d probably have to because we are in school and can only work certain times. as well as if we are working together, if one of us is a bad employee it could piss each other off. he didn’t see an issue with this and disagreed. what are your guy’s experiences or thoughts?
