I remember my DH telling me about his living in some construction sites in northern Alberta where there were wooden bunk beds with rough army blankets. People would come off shift and use the same beds as the crew heading off to work their shift. The only really positive feature for these crews was the food was top of the line available almost 24 hours a day. He would come home on a Friday for a weekend every 6 weeks and flying back to the site on Sunday afternoon. I finally told him that I wondered why we got married as the weekend was spent catching up on his laundry while he slept. Turns out that a lot of marriages didn't make it.
I was asking someone a couple of years ago who is on a construction site up in the northern areas what the accommodation and work situation was like today. It sounds like a 5 star hotel setting now - 2 weeks in and 2 weeks out. I mentioned a little of what it was like 50 years ago and he said that he would never have taken that job under those conditions.
Has the military accommodation and work situation changed as much, do you think?
