So i have had many opportunities to work nude. First off i have had many jobs and some it was normal to be nude as a figure model, other times when would go nude when alone at work and some where others we present.
Obviously as a nude figure model for art classes, colleges and amateur photographers i was completely nude for the sessions and most of the time while on breaks as well. Only time clothed was for showing up, leaving , and most of the time when leaving the studio for bathroom breaks. I have had some private modeling where would show up nude and a few locations where would not wear anything in hallways on breaks.
I also have taken massage classes and do some massage work on the side. I wear clothing to the comfort level of the client. Some like full street wear, some enjoy in only shorts, and occasionally enjoy me nude while working on them. In my classes i made it clear was a nudist , so would often be nude for instruction and demo time on the table for instructor. I did require draping when being practiced on by peer student practice and would put clothes on for being proper when peer working on another.
Other not supposed to be nude times include working as electrician and working in military armory. If was the only one on site would strip nude any chance i could. No one would see me except our secretary for one electrical co. She knew i was a nudist and would discuss it one on one with her all the time. Would even drop off weekly paperwork to her in office on fridays nude.
I remember someone on another board posting that at one time he worked at at farm where the owner required his farm hands to be nude whenever they were on the farm, except when they were in the process of arriving or leaving. If he caught one wearing clothes at another time, he ordered him to strip and hand him the clothes or pack up and leave immediately. The farm owner would then destroy the clothes immediately.
The poster noted that there was no physical contact involved.
No workplace at my location allows naturalist lifestyle, but yes I had worked naked the whole night in office when no one was around and when CCTVs were not mandatory. Now I work from home and most of the times I work naked. Though I keep clothes handy incase a delivery guys turns up.
Many years ago a colleague took his girlfriend (both nudists) to an out-of-town computer network and hardware installation project. It was for our company in an older office building. He had the weekend to do the work. It was summer and the office building turned off the air conditioning during weekends. When he returned he told me his girlfriend was nude while they were in the company offices.
