How can I have a lip piercing at work?

I had a lip piercing before and they had NO problem with it then one day I came in and they had me take it out and my hole got to small and I had to keep re stretching it 4 times a week and it got infected I tried spacers but the never really worked so I was wondering if there is another way BTW I work at arby's so and advice would be nice and no I can't get a new job I already worked here a year and Im 15 so jobs are hard to find at my age.
