Should the person who works from home do more household tasks than the one who doesn’t?

I think you should both do what you can, without spending your actual work time doing housework. Assuming as a joiner he starts quite early? Most that I know would start at 6 or 7 the very latest, so you have more time in the morning?
If he's back at 4, he can do some then. If he's not back till 7, you can. Doesn't need to be fixed rigid rules, just both do what you can when you can.

It's not about who works where, it's about who is free. So, if you work from home until 5pm but he works in an office but is home by 4, I'd expect him to do more as you're working longer hours.

If you're working from home, you are working, not running the hoover around.

I wouldn’t factor in working hours but I would factor in the commute. So if you both finish at 5 but it takes the other person an hour to get home then the person WFH could spend that hour doing some chores.

I can move laundry along during the work day if I am using the dryer, but that is about it. If I am hanging clothing that has to wait until the end of the day.

You should end up with equal amounts of leisure time. So if not having a commute saves you time, then you can pick up some extra chores. Otherwise, wfh shouldn’t really change the division of labor.

It depends how you do it doesn't it? Some people sort into colours, iron, fold and put away and see that as part of the job. I chuck everything in together, and when dry I make piles of crumpled clean clothes and dump them on people's beds to put away or not as they see fit. It doesn't take me long, but my standards are low.

You're working the same hours, so should be doing about the same overall.
If you want to spend all your breaks and your saved time from not commuting to do all the household jobs on your wfh days, then that would be ok but only if you are happy to do so. You could wear yourself out though, being non stop on those days. It depends how intensive your job is. If you can have a quick break whenever you want, then it might be quite easy to do put the laundry on while you make a drink. If you're non stop on calls all day that won't be possible.
You may prefer to do something for yourself in your breaks though, they are supposed to be breaks after all, and that would also be fine.
If your H finishes early then he should be doing some household jobs anyway. If he finishes late then you'd do more on those days presumably. If he's really tired (physical job) then maybe his jobs only get done on a day off.

All the people who start MN threads complaining how they spend virtually all their time sorting the washing.

(No, I don't understand it either).

I think you should strive for roughly equal amounts of free time. So I think its reasonable if you gain an hour or so through not having to commute, for example that your partner doesn't, then you could use the time for extra domestics. I don't think you should do extra simply because you're at home, cleaning in your lunch hour for example, when if you were in the office you'd be taking a break.

WFH I’d clear kitchen, load dishwasher , put stuff away and churn the laundry - The odd day I would cook but as DH is the one who insists on a ‘proper’ evening meal then he tends to cook or we batch cook and reheat. cleaner comes once a fortnight but around that I’d do little jobs , clean the loos etc

Who thinks it takes hours? Well it does take the machines hours, but not the loading, unloading and folding. In total, a load or 2 a day, maybe takes 10-15 minutes of my day.

Working from home means working so I would not expect you to do more for that reason. However there are some tasks that work well around working from home (laundry, vacuuming, putting the dishwasher on) that I would probably do more of that.

I don’t know anyone who thinks laundry takes hours and hours a week. Do these people wash everything by hand?

I always find it amazing how laundry takes hours and hours of the week for some people, but is also a quick job that can easily be fitted around wfh.

Well a bit more perhaps but not all, or anything like it. Depends how much time you actually have free compared to him.

You shouldn’t be short changing your employers to do housework, so as to leave him free.

That gets my goat (to use an old fashioned MN phrase) - when an employed partner takes on all of the household duties, days off with kids etc, to allow a self-employed one to max their earnings.

I don’t think it’s as simple as PP make out. I used to work from home 5 days a week and my partner worked in an office 5 days a week. I did a stressful job I hated and bought in 80% of our income. He did a passion project job he loved and was happy to spend long hours at.

id put on a load of washing between meetings or do the odd piece of housework. I’d start dinner because if we waited until he was home we wouldn’t eat until half 8.

it killed our relationship. I was earning more, doing more because I could. All I saw in the end was him having a lovely life facilitated by me

Take the "at home" bit out of the equation. You both work full-time, so, assuming these are equivalent full-time hours, you should be pulling your weight equally with housework.

That said, I don't think it needs to be a rigid split of x amount of hours each per day - you should adapt to what is reasonable within each of your schedules and hopefully it should settle into equal shares. As a PP has said, it would make sense for you to prepare dinner on these days as you are around earlier but there should be a trade-off for him. If you have the chance to stick on a load of laundry or whatever during the working day, then that's a bonus, but shouldn't be expected.

DP WFH and I don’t. I’ll come home and the washing has been done, washing up is done etc but not every day like I know he’s busy too. I’m really not bothered as he will just crack on and I have never had to ask. If he didn’t do it, I wouldn’t have a go.

I WFH so I do all the laundry. I also empty dishwasher 9/10.

That’s the only thing I do simply because I WFH so it’s easy for me. All other chores are split evenly.

If you are wfh it shouldn't be expected that you are doing more than very quick jobs while you are actually working.

Household tasks should be equally split amongst people who are at home and not working. So if you are wfh 9-5 you have more time at home than days you are in the office. Similar if your partner is home at 4, he has more time than if he is home at 7.

What about commuting time? My DH has 1.5 hours a day commuting time that I don't have on my WFH days. I can easily do a wash, empty the dishwasher and start dinner in my extra 1.5 hours. I can't imagine being so petty as to moan about housework not being 50/50 when I literally walk away from my desk at 5.30 and am in the living room!

When I am working from home I prioritise going out for a walk at lunch time to get some fresh air but other than that, if I have time to do some chores then I do. If I don't have time, then I don't.

I don't think it needs to be strictly even as long as everyone is pulling their weight.

Its too easy to think of WAH as not "proper" working and expecting to stop periodically to do this or that household chore.

And it depends upon how the working day is organised. If you are tasked to be available 9-5 (minus lunch break) then except for short toilet or coffee runs your employer will expect to find you at your desk. If however your work is like mine as an academic and is delivery based (you agree on a set of tasks and organize them to fit your own routine) then no one is going to expect you to sit at a desk for a rigid 9-5 day. With more flexibility you can put on a wash, peg it out, prep the dinner etc.

The partner who is working on site cannot be expected to do these things. however he can stop at the shop on the way home to pick up a few things.

When I'm working from home, I'll put laundry on in the morning and I'll put the dinner on in the evening because I don't have the 45 minute commute to do. I have the same working hours as my husband, but more available time, so it just makes sense for things like that.

You both work full-time so you do 50/50. You might work from home but you are working and you should be allowed a lunch break, just because you are at home doesnt mean you clean the bathroom or whatever at lunch time. If either of you were single you's have to do it all yourself, so 50/50 split when you both work is fair. If you worked part-time then yes you'd do more, but you don't so 50/50.

I also WFH 3 days a week and would say I do more than my husband who’s out the house 5 days a week. It’s easy for me to just put the washing on, sort tea out and keep on top of the tidiness/cleanliness of the house. It also means none of us are then doing much housework over the weekend! I don’t see why you wouldn’t do it if you’re at home during the day.
