***The night shift is a killer.***
This is true! I have worked mostly various shifts. I can handle 10 hours straight days or evenings.
First worst shift was military. 12 midnight to 12 noon.
Then 31 years if 8 hour rotating shift, often working double shift 16 hrs. Backward rotation. Midnights, evenings, days.
Then 8 hours of forward rotating shifts. Midnights, days, evenings.
Then we went to a 12 hour rotating shift. This shift was a real killer! 4 midnights. 6PM to 6AM. 1 1/2 days off, then three day shifts 6 to 6. Then 2 1/2 days off, then three midnights 6 to 6, then 4 days,6 to 6, then two weeks off.
You were constantly tired. Only in the last week of your days off you began to feel rested, then it was time for more midnights. When at work, I was requited to stay awake at all time. No cat napping, but you just could not help it. You would often be awake doing something, then wake up and find you had been asleep for a few minutes. Very dangerous!
Why did I stay? The money was great! Especially the overtime. Often I would get called in on my days off to work two to five days, all overtime.
I retired five years ago. It took me over SIX MONTHS to get caught up on 31 years of lost sleep. I still go to sleep very late in the night.
I absolutely LOVE my shift schedule. 0700 to 1900 4 days, 3 off, 3 on, then 4 or 5 off. 4 nights, 3 off, then 3 nights, and 5 or 6 off.
2 weeks of days to catch up on all the updates and other changes, then 2 weeks with no cretins underfoot so I can get some work done. It works great for me.
I declined a promotion because I would have had to work Monday to Friday 9 to 5.
