I'm a contractor. I had an opportunity to do a concrete job at a nudist resort. The pour was big enough that I needed the help of one more finisher besides myself. The only concrete finishers I know didn't know about my nudist lifestyle. I struggled with the thought of pouring the concrete clothed or nude. If I poured the concrete with him as a textile, he would not have known I was a nudist. I wanted to pour the concrete while nude, so I did. The other guy didn't know I was going to be nude until he showed up to the job site. He was surprised to see that side of me, but he said he didn't care. So with this incidence in mind, if another co-worker wanted to friend me on this site I would accept. It would be nice to have someone local to hike nude with.
Retired so work wouldn't apply. Would accept a friend request from someone in one of my community organizations. In fact, two of my band colleagues are also nudists and we quietly discuss this occasionally, we have not done any nude activities together.
I'm assuming that the question posed refers to a friend request specifically on TN. The bigger and more important question is if I want to make a friend at work. If the person is a friend, or friendship material, than clothing options mean little. If you're working at the same company in different department it's not really an issue. On the other hand, many employers may encourage camaraderie, but their culture becomes more frenemy.
We live in a small rural community. But we work at the biggest supermarket in town. We are lucky to know and be friends with several coworkers that are nudists. Every body knows every one else's business. We work together all day long and in the afternoon we swim together naked. Not aproblem.
