I think it depends on the type of work and the employer. I work part time, 2 days per week as a legal secretary. I go into the office, do my job and when I leave the office, I leave work behind until the next week, I don't give it a second thought. It never interferes with my family life.

My employer is fantastic and while my DD is with my MIL when I'm at work, if for some reason I need to swap my days to accommodate her, it's never a problem. I'm swapping my days next week so I can take her to a Play School concert

The extra money I bring in when compared to the effort and time I need to put in away from my family is amazing and for this reason, I will probably go back after my 12 months mat leave when this baby is born. It's just too good a job to give up.

I do understand that not everyone is so lucky with their work arrangements though.
