What time do you wake up and what would be your ideal time to wake up in the morning?

I have always worked shifts. First job was Monday to Friday, one week was 06:00 to 14:00 and the next was 14:00 to 22:00, rotating each week. Then I started another job which was the same hours as above but with a night shift as well, 22:00 to 06:00, and I worked a week of earlies, a week of nights, a week of lates, rotating. 17 years ago I started working 4 on 4 off, initially just days 06:00 to 18:00 and after about 3 years, nights were introduced, it was a brand new factory so we were slowly building up our production. Initially it was 4 days, 4 nights, rotating, then we done 2 days and 2 nights in each block of 4, which was better, but the upper management decided to put us back on 4 days, 4 nights, rotating. One year ago I started the job I do now, 4 on 4 off permanent nights, which is perfect. 4 on 4 off is probably one of the best shift patterns in my opinion, yes you work weekends and bank holidays, but you have plenty of time off to do what you want, and you only actually go to work for 6 months a year, then add in your holidays, which are a minimum of 20 days per year, and you are going to work for less than 5 months a year. Also, when using holidays, if you take 4 days holiday you have 12 days off because you have your 4 days rostered off, 4 days holiday, plus the next 4 rostered off. Take 8 days holiday, 2 blocks in a row, and you have 20 days off in total. People who work Monday to Friday each week, with the average 28 days holiday (inc. Bank Holidays) go to work for around 8 months a year.
