For those of you that do not know, I am a HVAC/R Service Tech. I have been on call for the last week, it has been well below zero all week, this morning it was -39. Since 8:00 am Thursday (the start of a new pay period) till 5:00 pm today, I have worked 24 hours regular time, 39.75 hours overtime, and 21.5 hours double time. I figure that is a total of 106 hours, and I have worked 85.25 of those. As of 4:30 pm today I am off call until next Monday. I do not even feel tired, I am sure it is going to hit me like a brick.
