I guess it depends where you work, I have one ear piercing, had it for 30 years, just a very small silver hoop, I've worked in the motor trade, retail sector and engineering, and was never a problem, the only job where I never wore it was when I worked for the PGA (professional golfers association) I didn't where it to the interview, as I knew it wouldn't be acceptable, never been an issue...you don't get an earing to "be cool" anyone thinking that or doing that, just doesn't get it....but hey, we all have different belief's. ..and without those kinda people...us "cool kids" wouldn't be cool!
