It’s really quite simple: just make sure that your union-protected work rules mean that you’re almost impossible to fire. As the Spokane (WA) Spokesman-Review reports:

A Spokane teacher is still being paid seven months after he resigned for viewing large amounts of sexually explicit material on his North Central High School computer…

By accepting his resignation the district assured that Wakabayashi was immediately removed from teaching, and the district avoids a lengthy investigation, officials said.

“When that happens the employee continues to receive pay until the matter is resolved by a hearing officer through a very lengthy legal process, usually lasting 18 months,” [human resources director Barb] Wright said.

For the record, Matthew Wakabayashi started teaching at his school in 1974. Remember that next time a union officer defends (with questions like “Why does it take so long to figure out if someone is a bad teacher?”) the practice of giving teachers lifetime job security after just a few years.
