Refusing to wear Safety Glasses!

Lately everyone wants too know what's going on with the union. For those who don't know, here's a little recap. About a month ago the union got voted in. Right now it's in collective bargaining. I'm not for the unoin in this particular shop. It's a small shop with 5 people, under me. I make it a total of 6. The vote was 4 to 2 : (

This post is about the company taking nessacery actions to keep the workers safe. Safety Glasses now have to be worn in the shop while working. The company bought everyone one pair, if anything happens to them they will have to replace them. One of the workers wears glasses, and isn't able to wear the pair the company provided. I asked for him too pick up a pair over the weekend, and the company would reimburse him. The following Monday he came in with nothing, saying he went to Home Depot, and they didn't have any that would work with his glasses.

I then got a pair from Graingers for him that sits over glasses. He ended up complaining about them messing up his vision. Eventually it came down to telling him he has to wear them or he can't work, so he chose to leave. The next day he came in with corner lenses that slides on the side of his glasses. These were aceptable.

The problem is the unoin thinks he should get paid for the day he left. I'm not sure why? On top of that, over this weekend his glasses got broke. Guess what pair of safety glasses he chose to wear! The ones he wouldn't wear the day he left. Why could he wear them today and not the day he walk out.

Please let me know what you think about this situation! Should he get paid? I'm I dealing immature adults?
