I have always worked full time, mainly because I have a mortgage and bills to pay, and I have never had proper support from Ex-P.
It is a struggle. DD has SEN, so needs after school care. It is unlikely that she will ever be able to come home from school alone.
I am constantly knackered. and when at work I am always clock watching. I can't really afford to be flexible - I have to leave work in enough time to walk to my car and pick DD up from the after school club. I can't do early meetings as I have to wait until DD is picked up by taxi in the morning. So, sometimes I feel that I am not performing well enough at work, and end up taking work home, which I do once DD is in bed. My job is pretty stressful, but I know that I am lucky to have a job, so also pretty worried that my lack of flexibility means that I might not be so lucky when the next round of redundancies come around..
I have negotiated one day a week when I can finish earlier, to collect DD and take her to a club and that is "our day". She loves it when I meet her from school. However, I do have to make the time up.
As far as housework goes, well, I do the bare minimum. It's just me and DD and we don't care too much about the mess. I do hardly any ironing, fold and put away clothes as soon as they are dry, and am amazed how much time that saves. My house is quite shabby, as I can't really afford to do it up, but we don't mind 
Her father is as good as out of the picture, for all the times he sees her, so it is all down to me.
If I'm totally honest, I would love to reduce my hours, but I can't afford to and would probably not find another similar job. I am quite limited in how far from my home town I could venture, as well as finding something that fits in with the times I need to be available for DD.
On the plus side, I enjoy being me, not "Mum", and I do like the challenge of my job. And for 8 hours a day I get to do the thing that I have studied and trained for, and feel competent at (being a Mum is tons harder and I often feel I'm not getting it right)
