When will journalists like Klein stop using phrases like "the stranglehold of teachers'-union work rules"? In addition to keeping conditions reasonable, the union protects students, as it did when a fellow teacher was recently forced to accept 37 kids in her class, many of whom were struggling. After the union stepped in, the district hired another teacher.

Concerning "Traffic Gem" [Feb. 7], on the diverging-diamond interchange: Why couldn't the approach leg on each side elevate earlier (or later) than the oncoming traffic lane, crossing over the oncoming traffic and thereby eliminating the need for traffic lights? In this case, it seems more traffic lights would only create more hazards while gumming up traffic flow.
