Acas, the conciliation service, says that outdated views about tattoos mean that companies are missing out on top talent. It says businesses have a smaller pool of people to employ. That, of course, can work the other way with people with tattoos having a smaller pool of employers willing to take them on.
I do not have strong views on tattoos in general, but I often find that those with them do not usually fall in the 'top talent' bracket, especially those who keep having them done into later life, so I wonder where Acas got its evidence from for that claim.
On the other hand I know many bright people who, in a moment of madness, had a forearm tattoo done when they were in their teens. Many of those now keep them covered when at work or in polite company.
A persons body is their body and, within reason, they are free to do with it what they want, but it is not for Acas and their likes to drive an acceptance agenda on those who do not like what they see.
The real story is the opposite from what Acas is saying, but to put up "Those with tattoos have a smaller pool of employers willing to take them on" is so politically incorrect it would never be allowed.
