Our company have a "progressive" work policy where, if circumstances permit, women (or men) can "job share", work from home and/or work reduced hours. Good loyal employees are hard to find and keep, so our company tends to be flexible as long as the corporate objectives are met. No, we still do not yet allow employees to bring their babies and/or dogs to work.
Maybe your wife can negotiate a more flexible work schedule rather than quit "cold turkey".
