Piercings and work

I have my first and second lobes both healed and can put clear retainers in my seconds but I got my conch pierced a month ago and can’t take it out or put a clear retainer in it while I work (I woke 8 hours at a time and handle food) my mangers haven’t noticed it yet since I work pretty much away from everyone else but I want to know how long should I wait to get a clear retainer? Or how could I hide it better since I have to wear my hair up, my friend told me I could get a doctors note that says I can’t touch it or take it out till it’s fully healed since it’s classed as a healing wound but I just wanted another option

Thanks
