Just a quick job question to any one who knows the answer?

i live in connecticut, i have a part time job at a video store, this past weekend we suffered our first snowstorm of the season, i am only scheduled to work 1 day a week. however im a good worker (i thought) and called my boss saturday afternoon and let her know that i wouldnt be able to make it in on sunday if the weather continued the way it was. she said noone in the store is available to work, so i called other stores, to no avail, noone could or wanted to work. evidently she gave everyone who wrks in our store the night off. she also told me that shed hate to see me miss my only shift of the week because of the weather, which to me sounds like she'll understand if i couldnt make it to work. sunday comes round and i can see that where i live travel was going to be dangerous, at 5pm when i had to b there and especially more so at 10pm when my shift ended. so i made a safety first call and told the t manager that i couldnt make it. needless to say that when i tried to find coverage again noone wanted to work. apparently not the store manager or the istant manager who by the way lives about 5 minutes from the store. when i went in on monday night to talk to my manager, and check the schedule i noticed that on the 28th i was scheduled to work but my name crossed off. She also informed me that i wouldnt be spoken too until after the holidays. so now i have to wait at least a week to find out if im fired or not and this being the holidays thats just not right. Now my question is basically, what did i do to warrant that. and is there any thing i could say or do legally. i have no verbal warnings, or written warnings about this. this was my first call out, and yes i did call out. the day before actually, and i talked to the store mangaer about it, but because she drives a truck and lives closer to the store than i, she says the roads were ok enuff for her to drive on. not in my car it isnt. y put myself or any one else in jeopardy because of a job that im only scheduled to work 1 five hour shift where im also not even insured to protect myself from an accident or its cost. the more i think about it the more i realise that my rational way of thinking was wrong, i just umed that as a store manager or istant manager that they were on call as much as possible, and the istant doesnt work more than 25 hours a week so its not a case of him working too much, but as management isnt part of the job to work when noone else can, i did when i was a store manger at 3 different places. Also i always thought that when doing the schedule its first come first serve when it comes to days off, you cant give the other 7 employees the same day off, but again maybe im in the wrong. please let me know what u think about this subject.
