Hi wendy! this is wendy!
I used to work for a company like that. They threaten you so you will come in. Wen....your family is your life. They have to come first. If your DON doesnt understand that it is not possible for you to leave your children ALONE IN A SNOW/ICE STORM then you dont need that! If they fire you, let your good work record speak for itself and tell your interviewer the truth...that you were fired for not leaving your children at home alone.
Don't let them guilt you into making a decision you could regret for the rest of your life. What if your kids lose power? They will need their mommy more than your patients will at that point. They are really calling for this ice and snow to hit us (I am in Knoxville).
I was just sitting here worrying what I was going to do when noone showed up at work in the morning. (I am the weekend supervisor so I guess I will have to go in at midnight tonight

). You made me remember what is important.
Thanks to you, I will remember not to get angry at my staff when they can't come in because of the weather.
We will take care of the patients. You making sure your kids survive this coming storm is most important for you.
Just remember about this weather coming...It is what it is! We can't stop it, we just have to deal with it.
Do what you need to do for the storm and don't feel guilty!
