Discussable items for teachers.

Requires a school employer to discuss certain items with the exclusive representative of certificated employees. Provides that the obligation to discuss does not require either party to enter into a contract, agree to a proposal, or make a concession related to the discussable items. Makes it an unfair practice for a school employer to refuse to discuss certain items with an exclusive representative. Removes language that excludes a discussion or meeting to discuss items between a school employer and an exclusive representative from the provision that establishes instances in which executive sessions may be held.
