Being taped to a chair like that, yes, it has happened to me (more than 35 years ago) - but without the gag.
No reason, and no idea why they did it to me, other than they thought it would be 'funny' I guess. I was not amused, did not report it either, although back in those days it would have been dismissed with that ever-handy "boys will be boys".
This hostile work environment for women is why women are reluctant to enter, or stay, in many of these male-dominated workplaces. I just think back to the other thread (was it the t-shirt one?) with some of the cool women tutting 'other women' for not toughening up and going into these sectors. Hazing, harassment, sexualised remarks. I think I just learned to be observant and side-step situations before they occurred.
