Tex. Loc. Gov't Code § 143.362
Within 45 days after the date an agreement is ratified and signed by the municipality and the bargaining agent, a petition signed by a number of registered voters equal to 10 percent of the votes cast at the most recent mayoral general election in the municipality may be presented to the municipal secretary calling an election for the repeal of the agreement, in which event the governing body shall reconsider the agreement, and, if it does not repeal the agreement, it shall call an election of the qualified voters to determine if they desire to repeal the agreement. The election shall be held as part of the next regularly scheduled municipal election or at a special election called by the governing body for that purpose. If at the election a majority of the votes are cast in favor of the repeal of the adoption of the agreement, the agreement becomes void. The ballot shall be printed to provide for voting for or against the proposition:
"Repeal of the adoption of the agreement ratified by the municipality and the police officers of the municipality concerning wages, salaries, rates of pay, certain benefits, hours of work, and other terms of employment."
