I used to work in a hospital and there were a lot of staff, nursing all the way to maintanance, that had visible tattoos and the hospital was ok with it. except this one girl who was a CNA had profanity written down her arm and they made her wear a lab coat at all times. if she were caught without they would send her home. and now i work in a doctors office and one girl there has tattoos all over and they hired her with no questions about it. so i guess it will depend on where you work and what your tattoos are
