Having worked in factories for the past decade I've never had any issues. As a lead mechanic/supervisor I visited a couple major pharmaceutical plants to see their plants and how they used our products and wasn't asked to wear long sleeves(I did, if it matters).
I recently left my job at Pepsi to help run my families businesses, we have 4.. The majority of my time is spent on our painting business which is quickly approaching 30 years old. The majority of our work is high end custom residential and we work solely on a referral basis and have never advertised. I meet with homeowners and the contractors regularly, one or two have been a little apprehensive at first but once they realize I know exactly what I'm talking about that goes away..
My plans are to keep my tattoos coverable by long sleeves and long pants, IMO what goes on under those is my business, period.
I'll spend my life middle class living how I want to Vs giving up my own dreams to make others come true.
