I have owned my own business,and would work strange hours when my son was little,i.e.when he was sleeping at night. I have also done jobs where I would leave home very early to get to my place of work on time when I was doing an apprenticeship.
Yes. My standard hours in Singapore were 8am to 3am, seven days a week. Not so unusual in the finance industry but it raised an eyebrow or two amongst friends and family who had no experience of the City! If I worked all night I would insist on going home for a shower and a nap. There are limits!
As a childbirth doula I go and attend my client once she goes into labour. This means that I could get a call at any random time of the day or night and could be working for anywhere between 2 - 24 hours. My first client I got called to attend her at 2pm and was with her until 12pm the following day. The pre-natal appoints are of 2 hours duration and are done at a time that is convenient for the couple and me - so it could be during the day, or on a weekend or in the evening.
Weirdest hours I've ever worked were as a kitchen hand in a convention centre where I worked 5-12 pm on weekends although I must say I preferred these hours to my other job at the time that was 6am - 2pm weekdays!
I am an Industrial Engineer, which means I analyze work to determine productivity and problems. One place I worked had 3 rotating shifts. I had a complaint from a worker about a problem on the midnight shift. I had to work all 3 shifts to determine a resolution. I did this within a month.
At another place, I worked 4x10 hour shifts - 6am to 4:30pm. Making it worse was the fact that I had 1 hour drive in the morning and 1.5 hours going home. I was asked to analyze work on the second shift - 6pm to 4:30am. On top of that, I had to work day shift on Monday, 2nd shift Wed-Thurs and days again Saturday. I was dragging for an entire week afterwards.
I’ve never had to work funny hours, but my husband had to work 3 different shifts of his 1st 16 years in his last job, & then he was put on day shift for the rest of his time there, which was another 17 years. Our daughter’a partner does awful hours of shift work, where he works in a paper recycling plant.
