I am a huge fan of tattoos. I am currently just about done doing my sleeve on my right arm. Now my take on the whole subject is, it is not professional. I have many tats, but I can cover it up with my work uniform. Now in a professional work environment, I would find that stuff to be a bit much. All depends on the persons profession. If I were to go to a job interview at lets say a high executive position, and I was against another individual with the same qualifications and he or she was not covered in tattoos, that other person would probably get chosen due to him not being sleeved. If there was a work day where they had to wear a short sleeved shirt, they would not want someone sleeved up representing their company. That is how I feel about it.
