Google first began offering day care three and a half years ago, and perhaps it is only coincidence that this occurred not long after a woman named Susan Wojcicki returned to the company from maternity leave. Ms. Wojcicki is a figure of significant stature at Google; hers was the garage that Mr. Brin and Google’s other founder, Larry Page, rented while starting up Google. Today she is the company’s vice president for product measurement, though as I discovered in talking to unhappy Google parents this week, not many Googlers seem to know what her exact duties entail. Everybody, however, knows that she’s Mr. Brin’s sister-in-law.

From the start, Ms. Wojcicki has been a passionate advocate for Google’s day care efforts, though there is some dispute about how much decision-making authority she has. Parents who know her point out that the company’s day care approach is very much aligned with her views; for its part, a Google spokesman insists that “these decisions were not made by her; they were made by the executive management team.”

It was no coincidence and it’s probably unlikely that decisions “were made by the executive management team”; rather, they were probably approved without too much opposition. Google has shown that it makes bad decisions like other companies do.
