There's an Important Place in the Office for Rules of Etiquette
As illustrated by this post from Robin Shea, sensible etiquette can save companies from a pregnancy discrimination lawsuit. This approach is so wonderfully old-fashioned and commonsensical that I can hardly stand it.
The same principle applies to avoiding problems from a host of other kinds of discriminatory conduct.
Bravo, Robin! If more lawyers thought like this, employers would have fewere problems with the law.
