How long does it take for a Tragus Piercing to close up?

I've had my Tragus pierced for around 3 years now but I'm not allowed it in for work - how long will it take to close up? I have breaks every 2 hours and was thinking of just putting the bar back in every break but would this irritate it? Thanks!

Yes, replacing it that often will definitely irritate it. Are you allowed to wear a retainer? You can get a clear glass lip retainer and it'll hide it pretty well. There isn't a way to tell how long you can leave it out. It depends on your body.
