Is this legal?

Ok, so a few weeks ago the intelligent W-S/FCS system, on the forecast of "big snow", closed schools almost 18 hours before any precipitation was supposed to begin. Well, the even more intelligent people at Youth Opp decided that since the kids were out of school and they wouldn't be making any money that day, they should close down the program and tell us not to work. Ok, fine. Yay snow day!! But no-no, it wasnt just a snow day... we were forced to use our own PTO (Paid time off) that we get so little of. (After working for 6 months, you get 6 days off. The first 6 months you work there, you take days without pay if you can't/don't come to work. Then, after a year you get another 8 days. Then, and only then, after you've given a year to the company, do you being earning more PTO at a rate of 5 hours per pay check.. the biggest bunch of bull shit ever!) Anyway, almost everyone there is a newbie, having been there between 6 months and a year, so none of us have very much time to take off, and they forced us to use it on a day we could have easily done planning, caught up on paperwork, or even gone to see families. Because, as usual, there was no bad snow. So, my question to my readers is: Does anyone know if this is legal for them to do? I've looked it up on the labor website, but it's not clear in their FAQ section whether it is or not. I have a phone number to call, I just need to do it, and hopefully talk to a person so I can spell out my question specifically to a HUMAN.

Grumble.
