Growing up, my Dad had a few years working odd shifts. 3rd shift was the hardest on him physically as he had a really hard time sleeping during daylight hours. 2nd shift was the one that made him demand a return to 1st shift. There was about 18 months where I lived in the same house as him and literally never saw him. He would leave before I returned from school and arrive home after we were asleep. In the mornings, we'd be off to school again before he woke up. Combined with him having to work 3 of 4 weekends a month, it was hard on all of us. He did what he needed to provide for us and I am grateful but I'm more grateful that he's enjoying a decent retirement today.
