Airlines for America has filed a lawsuit against a new Washington state law that mandates employers provide paid sick leave, The Seattle Times reported Wednesday.

The law took effect Jan. 1 after being approved by voters in a state ballot measure in 2016. Under the new law, employees are entitled to one hour of paid sick leave for every 40 hours worked. It applies to all employees, including seasonal and part-time workers. Washington residents also voted to gradually increase the minimum wage to $13.50 by 2020.

A4A argues in its lawsuit the law is unconstitutional for Washington-based pilots and flight attendants because they spend most of their time out of state. The association also argues that airline employees already have generous sick leave benefits because of collective bargaining agreements reached with the unions.

Unions representing flight attendants and pilots told the newspaper they would fight the lawsuit.

"As long as airlines operate in the state, they are subject to state laws," Sara Nelson, president of the Association of Flight Attendants-CWA, said in a statement.

The lawsuit was filed in U.S. District Court in Tacoma. http://bit.ly/2ERmiOG
