On the topic of "relative" stress. My mother never worked fulltime - she married young, and was a SAHM even after my dad left. After all us kids grew up she started working a few hours per week. Don't get me wrong, she is a *very* hard worker, just her way of working is different and more flexible - it's all been around household duties.
A few years back she got a paid job that would require her to work twice per year for 2 weeks straight. (Kind of like working the door at an event). Prior to the event she had a few hours of prep work / scheduling to do from home for two weeks, but mainly it was just those 2 weeks of work. Note that this wasn't a second job, it was her only
paid job at the time.
During those two weeks, the way she would complain to my sister and I about how hard it was - sheesh! Do you have any idea how hard it is to get your laundry washed and dried, and get dinner cooked, when you have to leave the house by 9am and don't get home until 5?
....Well, yep, sis and I both did - we both worked fulltime and had done for many years! Back then I was leaving the house at 7am for my fulltime job, home around 6:30pm, and that was 52 weeks of the year. Oh and did I mention I was also completing university studies part-time in the evenings, and planning my wedding with DH?
I was understanding because I knew that to her it was a big change and a big deal. But I can't say I had a lot of sympathy
