(a) A municipality may not be denied local control over the wages, salaries, rates of pay, hours of work, other terms and conditions of employment, or other state-mandated personnel issues.

(b) An agreement under this chapter must be written.

(c) This chapter does not require the public employer and the recognized employee association to meet and confer or reach an agreement on any issue.
(d) This chapter does not authorize an agreement regarding pension or pension-related matters governed by Chapter 358, Acts of the 48th Legislature, Regular Session, 1943 (Article 6243g, Vernon’s Texas Civil Statutes), or a successor statute.
