Ok. I have a question: What do y'all think of dangly earrings at work?

I put a pair on this morning, and then took them off. They were "punky" bows (kinda like the pic below, but not *pearl*). Now, I can wear them in the office, but if I go on to the factory floor (unlikely today), they have to come off. I was thinking they made it seem like I was unprepared to work.

I note, too, that dress codes for hotel hospitality planners and so forth also specify discreet button earrings - no dangling earrings. And they have no safety concerns.

Thoughts?
