Bonni - I absolutely agree with the positives of doing compressed hours.
Prior to having DS I had a Mon-Fri job, 9-5 hours and when I planned to return after maternity leave I asked to reduce my hours as I didn't want to be away from DS that long. However, they said no and so I resigned and got my current nursing job which enables me to have 4 days a week at home.
I imagine a lot of people probably would be envious but it does have its downsides too. I leave my house at 06.50 and don't get home until 21.30pm, which is a long, long tiring day, and when I do that two days in a row I am exhausted by the end of it. I think we spend half our time off just recovering from the shifts we do, I never feel particularly sprightly on my days of and usually I don't have the energy to do anything of quality with DS anyway.
My shifts also mean that as I have to work one weekend day there is only one day in the week where me, DH and DS can spend time together and sometimes I'm too tired to even enjoy that. Some weeks I work Saturday and Sunday which means we have no quality time together as a family. Plus, I doubt many other parents only see their child for a total of 1 hour in the space of 48 hours due to their shift patterns.
On the days we're off we do all the childcare, the housework, the cooking, the admin jobs, the shopping etc We have to take the children out to groups, play dates, attend social events, visit the family with the children etc and all because we're the ones at home whilst our partners work "full time". I think parents with such compressed hours have the role of a SAHP whilst working full time too.
On the surface the concept of only working three days a week may seem wonderful but the reality of it is actually quite the opposite.
I'm not being a martyr because I do love my job and I appreciate that there are benefits to doing compressed hours but there are also a lot of downsides too when it comes to home and family life.
I often wonder whether I should have stayed in my previous job where ok, DS would have spent more time in childcare but it meant I would see him every day, be there for every bedtime, I wouldn't be exhausted 90% of the time, I could have every weekend off to spend with my DH and DS as a family and things would be much more equally split in terms of childcare, housework and household duties as opposed to be being responsible for about 80% of it all because I'm at home more than DH is.
