A Wayland educator has received a written warning from the state after sending an e-mail in April to school parents, urging them to vote for a $1.86 million property-tax increase largely earmarked for schools.

Wayland Middle School principal Charlie Schlegel was found in violation of state election regulations, following a complaint made to the Office of Campaign and Political Finance. The complaint centered on an e-mail sent by the principal, using the school’s system, urging parents to vote in April’s election and support the Proposition 2 1/2 override on the ballot.

The Boston Globe has the story.
