I also think that "just going back to work" is so much easier said than done.
That's for sure. I looked for a few months last year but stopped as there was a series of family crises to deal with and I didn't have the emotional strength or motivation to continue. It's really hard to get back in, though I think I would have eventually gotten something if I had persevered as I was working on a certification in an up and coming area to differentiate myself from the pack. I was shocked that I even got interviews, but I think it helped that I dabbled in it most of the time I was home. If you think you will eventually go back, I think it's important to keep up the skills somehow, even if it's through volunteer work.
here's another issue that came up for me: As the kids get older and parents are aging, I found I had additional responsibilities and, as a new employee, I wouldn't have the flexibility to take off when I needed to. Whereas my WOHM friends are at that stage in their careers that they can do that and WFH as needed, etc.. It takes time to build that sort of rapport with an employer.
I was fortunate that I didn't need to go back and, frankly, I no longer want to. I've figured out other ways to use my skills (volunteer work) but these are all issues to consider. In the end I have no regrets as SAH suits me. And like PP said, I didn't think about the practical stuff when I quit - it was a very emotional decision for me.
I didn't catch the fact that this author has written several books. I think she's trying to get attention for book sales. It doesn't make her points less valid on the whole, but I get the feeling she is trying to spur controversy for publicity sake so I have to wonder if those are all her true feelings.
