Tattoos, Piercings, Workforce

In the workforce today, they are saying how you can't have any tattoos or piercings because it is unprofessional. But why should these things be counted against someone who does a great job. I mean to me if they are a great worker, then who cares what they look like or have on their bodies. I personally have a tattoo on my lower back, and several piercings, one in which is in my eyebrow. Now at my last job I worked as a Manager of a shoe store and when I started there my boss had a nose ring, and it didn't matter. To me it really shouldn't matter and it seems that because of how tattoos have been represented in the past people see them in a bad way. Same thing goes with piercings and I think that yes, in some industries they shouldn't allow them. But in others they choose not to allow them and I think they could. Unless the piercings or tattoos get in the way of them doing their work somehow then I think they should allow them. I think that if they allow people to express themselves and be comfortable then they will work harder because the will stop worrying about what others think about them. I feel this way because my last job allowed me to be myself and because of that I felt more comfortable at work and was able to do my job better. I stayed at that job for 5 years and the only reason why I left was because I moved to go to college. I loved going to work and being myself, if all jobs were like that then I think workers would do better.
