I encourage you to read Lynn's summary, but in a nutshell, here are the five work styles she identifies from her studies:
The parenting style of a working mom who is a lawyer will dramatically affect her engagement in all facets of professional development, her frustrations, and her career trajectory. A woman who fits the "parentess" model is likely to be quite content with a stable income, nonequity partnership, or even staff attorney, at least for some portion of her career. Nothing wrong with that, and progressive law firms are well advised to make this option a real option for women (and men, for that matter).
But women who see themselves as "Workables" or "Equalizers" probably have a strong desire to succeed as a professional, and accordingly won't be content with the career and advancement limitations of nonequity or staff attorney type jobs. There is much that can be done by law firms to make this a realistic alternative for motivated and talented women who want a satisfying career, and a family life. .
