Last year I asked my co-worker what temperature it should be that we don't show up to work? I was told that when it's not -50ﾟF by 6am then we should come to work. Well, It was -49ﾟF by 6:31am. It was too cold for me and for my truck so I called and stayed home. By 9 am the temp reached -50ﾟF (I didn't get to capture it) but the employees who should up at work was sent home.
