OMAHA, Neb. (AP) — Omaha Police Chief Todd Schmaderer and his assistant chiefs are in line to see salary increases under a new agreement with the city.

Schmaderer will see a raise of more than $6,000 this year under the tentative contract agreement between the City of Omaha and its police management bargaining unit, which includes Schmaderer and the assistant police chiefs.

The agreement, announced Friday, includes an 8 percent salary increase for all police managers over the four-year contract.

The city has struggled to retain police chiefs. Schmaderer’s predecessor, Alex Hayes, served as chief for two years and retired at age 48 in 2012.

When Schmaderer was hired, he was Omaha’s fourth police chief in five years.
