One of my instructors had his arms all tatted up, his response to patients criticizing them was I could go and you could call for another ambulance but their probably going to just send me again.
I thought I had explained this in an earlier post but I will clarify it.
Hospitals usually have policies against any visible tattoos. In the past tattoos were okay if they could be covered up with clothing (not bandaids on hands). For infection reasons, long sleeved clothes are now no longer permitted in many ICUs and certain floor units. If you have visible tattoos you may be asked to transfer to another unit which does still allow tattoos to be covered or you could be terminated. Since this is a policy which is directed towards patient care, unions will not defend you nor would you be hired for a position if you have tattoos visible.
