Help desk guy caught jerking off at his desk by a female employee, which he had apparently been doing for a while without a whole lot of cleanup, further investigation uncovered.
His keyboard, mouse, desk, floor mat, and chair were disposed of as hazmat. Monitor and PC were e-cycled.
I used to work tech support for a company that made a product which involved sharing live or recorded videos. We would use the same instance for testing and troubleshooting, which occasionally involved broadcasting live videos.
One morning, I signed on to look for something or other, and I saw that one of my co-workers (who was working from home) had a live feed. His camera was pointed straight at his crotch and he was going at it quite vigorously. I deleted the feed and I don't know if he ever even knew what happened.
