We employ people regardless of tattoos and / or piercings and have, hold the front page!!! never noticed that it makes any difference whatsoever to their work ethic, their standard of effort and achievement within the work environment or that customers have run screaming terrified from the premises, in fact there is one very heavily tattooed and pierced young man who is a bit of a hit with the older ladies ( who don't seem off put or horrified) because he's so polite and obliging.
It doesn't matter. I don't care if my mortgage broker, bank manager, hair stylist, surgeon is tattooed or not, I just care how good they are at their jobs. This isn't the 1800's, it's the 21st century we should be above all forms of discrimination including this.
