Decision 0240E – San Jose Community College District

District's tentative calendar, because it merely established date for student attendance, as opposed to changing the certificated work schedule, was not within the scope of representation.

District's decision to substitute teaching days for in-service days was non-negotiable; no evidence was presented showing the District's actions impacted upon hours, or another negotiable subject; no evidence presented to show the change increased preparation time or use of off-duty time for meeting professional responsibilities.
