Hey man—This is a complicted investigation. It’ll take (hopefully enough time for the incident to be forgotten). I’ll demonstrate how compolicated this is:
Investigator to teacher: Did you send the email? Did you send it on a school computer? Did you send it on school time?
Answer: Yes.
Investigator to school board. Do you have written polices agaist using school equipment and time to promote a political agenda?
Answer: Yes.
Conclusion: Teacher violated written school policies.
Punishment: If a first-time offence teacher should be placed on one month unpaid leave of absense. If a repeat offence teacher should be fired.
Now, wasn’t that complicated and time consuming?
[Don't call me "man"!--just kidding, although I prefer to be just one of the guys (in MN we called everyone guys whether male or female)]
