Education Sector has an excellent explainer on teacher contracts that compares and contrasts the San Diego Unified School District’s contract with a typical contract used by Green Dot charter schools with its unions. The explainer goes provision by provision, covering things like teacher evaluation, pay and benefits, layoffs and dismissals and grievances and disputes.
The current teacher and paraprofessional contracts between San Francisco Unified and United Educators of San Francisco are also posted on the UESF web site.
