Isn't VTA prohibited by federal law from politicking on campus?

Roxy asked at "Do federal laws prohibit UNIONS and PUBLIC OFFICIALS from politicking on PUBLIC SCHOOL GROUNDS?"

Roxy I am not sure but I do know that the school district has rules about political organizing during school hours. This issue became a campaign controversy when ANTI public education candidate, Stephen Guffanti violated this school board policy during the last election.

Teachers are highly restricted from political action. Bush era National Labor Relations Board decisions by Bush appointees restricted unions from contacting membership through company (district) mail or email, passing out campaign literature to students or parents during school hours, wearing buttons advocating a politician or political viewpoint, political posters in their rooms, etc. (with one exception--high school civics classes where local elections can be discussed)

However, Teachers ARE allowed to have bumper stickers on, or campaign signs in, their cars parked on campus. Political meetings after school hours are also allowed in school facilities.

Clear? Other questions?
