I took a term-time only job this year to fit better around our family. I used to be a SAHP but have worked FT for the last 4 years and PT before that for a few years. Youngest DC is starting secondary next week and eldest is starting 6th Form. DH is self-employed and primarily WFH. He earns a lot more than me. We had a two week family holiday at the start of the summer holidays.
When I started working FT, DH had to step up in terms of helping around the house. It is a general bone of contention and tends to go in phases. He does a lot with the day to day but doesn't do the unseen bits (i.e will make dinner but wouldn't think to clean bathrooms or change beds etc).
My job is very inflexible. I start at 08 30 and finish (if I'm lucky) at 16 30. My day is full-on with no time for anything other than work. I also do the school run so leave at 07 15 and get back at 18 00 ish. DH has a more flexible job - he can take appointments, go to the gym and often goes to lunch with his family. We are a very busy household and someone has something on most, if not every, night of the week and most weekends. It is exhausting but ultimately that is the way we have chosen to live our lives so we get on with it.
Over the holidays, DH has stopped contributing in any way towards the running of our household. I get that I am technically off work (I have done some additional work but only 5 days) and for the most part I don't begrudge this. However, it's not like I've been sat on my arse. Most days have been taking DC to various things as well as trying to do the jobs that I never can in term-time I.e. decorating and clearing out etc. He has literally stopped doing anything. I have been out for two full days for an activity for DC and there has been a load of washing sat in the machine since then. He hasn't hoovered, cooked, emptied the dishwasher or reminded DC to do homework. Everything has come to me. We've had it out this afternoon and he thinks I'm being unreasonable. He said that he made the assumption that because I'm off then I'll do it all. I think that if you know I'm not going to be in then you'd at least empty the washing machine and dishwasher rather than leave everything piling up for me to do and that his attitude is really disrespectful.
