HB 4156 requires Oklahoma public school districts to include specific, clear categories in teacher employment contracts, such as detailed job descriptions, guaranteed 30-minute duty-free lunch breaks, and itemized salary and benefit breakdowns. It prohibits contracts from containing vague phrases like "all other duties as assigned" or requiring uncompensated work outside scheduled hours, while allowing compensated additional duties outside contract time. The law directly affects K-12 teachers in Oklahoma public school districts by mandating transparency in their contracts and compensation. It takes effect July 1, 2026, and applies to all new and renewed contracts starting with the 2026-2027 school year.
