I’m so sick of schools closing because of a light dusting of snow. Do they not understand parents still have to work?

Do you know for what reason your school was shut? In my area most teachers struggle through atrocious weather conditions to ensure that there is a safe building open for any students who have done the same. The school generally only closes if a majority of bus services are not running because of ice on the roads, or the heating has broken down and it is not safe for children to be there. The same principles tbat apply to my workplace.
