I don't have a full ½sleeve, but what I have on my arm is getting fairly close to being that. Like you, Paula, I'm in Europe, where there are less issues with this sort of thing. I work in an office environment, but when I have to go out in public to represent them, I just be sure to cover up as much as I can. Unfortunately, this type of society that we have to represent ourselves to professionally isn't always ready to see the art we have on our bodies. I too believe that will change eventually.
I'm going to get inked on my right arm too - for the balance

and personally everyone I know, knows I have these tattoos so weddings, funerals, that kind of thing, they know it could be shown and it's accepted. I try to be respectful of course, but ultimately, this is who I am, art and all, people just have to accept it or shut up!
