Yes employers will discriminate against you if you have visible tattoos. If you have something you really want though, i say go for it. You can cover up like 90% of your body for an interview and for a job even. (Unless its a really physical job, then you may not wanna be forced to wear so much clothing). The only areas i would try to avoid are hands, neck, and face/head. Almost everywhere else can be covered. I do believe the workplace is becoming more and more accepting of tattoos also. Which is of course a good thing!
