One of the city's largest employers, from 2013 to 2017, was Serco. The British-based company was awarded a five-year contract in 2013 to manage the implementation of the Affordable Care Act. As a result of the contract, Serco opened its Affordable Care Act application processing facility in Wentzville in August of that same year in the building that was formerly home to the US Fidelis call center. The Wentzville Serco facility attracted national attention in 2014 after whistle-blower allegations revealed that workers spent large amounts of time sleeping or playing games due to lack of work.^{[21][22][23][24]} At its peak, Serco employed approximately 1,500 employees in Wentzville.

Sally Hunt of Maryland Heights spoke to the Wentzville Board of Aldermen on February 28, 2018, regarding an "In God We Trust" insignia recently mounted on the dais.

According to the terms of the settlement, Wentzville law enforcement officers will not remove a person from a council meeting without probable cause.
