DH and I had an interesting conversation about this the other day.
We both work full time and don't yet have any DC. I am self employed, which means I can work from home some days, but frequent have to work very long days and my work is pretty intellectually and emotionally draining. DH's job is 9-5 and arguably not as intense as mine.
DH is far more domestically minded than me. He actually enjoys the little tasks of running the home. He does all of the washing up and cleaning the kitchen, and takes charge of the tidying, laundry, hoovering, bins. I do the weekly on-line shop, but DH does the top-up supermarket run every 2-3 weeks.
I sometimes 'help' with the tidying, laundry and cleaning, but would say that DH does 90%. I am in charge of cleaning the bathroom and my biggest contribution is cooking dinner, which I will do maybe 5 nights a week and either DH will cook or we will get a takeaway for a couple of other nights. I do the dusting far less often than it actually needs it.
DH does most of the house admin, such as renewing insurances etc, but I will arrange for any necessary trades to visit the house as I can work from home far more easily. DH does the maintenance for the car and bikes.
I brought up in discussion that it feels like I actually contribute less than he does to the running of the house, and if you added up the total numbers of hours a week this is true. He does still end up with more leisure time, as I work longer hours. When I said that I felt he contributes more, he disagreed. He pointed out that I do take charge of the garden (I came up with a landscaping design a couple of years ago and do a couple of hours a fortnight maintenance) and I take charge of the DIY projects (I have built some fitted furniture in our house as it currently is and am busy planning the interior design of our forthcoming extension and conversion). I enjoy gardening and DIY and see this as my hobbies rather than chores, but DH said that he values it as a contribution to our lifestyle and the general amenity of our environment. We agreed that it takes far more 'thinking' and skill than the washing up and laundry does.
Our household roles are pretty much reversed from traditional gender roles. I do wonder if we have a fair split. DH is happy, and he is the one who said that my DIY and gardening contributions may require less time to do, but have an equivalent 'value' to the more time consuming daily tasks that he does. I do wonder at this. Is it a fair comparison? Or is he automatically undervaluing the tasks that are traditionally seen as the woman's domain?
