The Harris County AFL-CIO Labor Assembly has declined to endorse any candidate in the Houston mayor’s race, the coalition of local unions announced Friday evening.

The group, which unanimously backed Mayor Sylvester Turner in 2015, voted to take “no action” after more than half the delegates at a Wednesday night meeting voted not to endorse Turner.

Candidates must earn two-thirds approval to receive the labor assembly’s endorsement.

The union coalition includes the teachers and firefighters unions, along with the local district of the International Longshoremen’s Association. All three unions have dropped their support for Turner after previously backing him.

For his part, Turner plans to roll out a list of labor endorsements Thursday, a campaign spokesperson said.

Unions affiliated with the assembly may issue their own endorsements in races where the assembly voted to take “no action.”

On Thursday, the local teamsters union endorsed Turner, citing the mayor’s response to Hurricane Harvey.

In a statement, labor assembly president Ginny Stogner McDavid, thanked members for attending the Wednesday night endorsement meeting “and participating in HCLA's ever-important mission of getting labor-friendly candidates elected to municipal offices here in Houston.”

McDavid continued: “It was a long process of screenings that started on 8/9, and an ever important one to ensure Labor’s voice gets heard at City Hall.”

The group also voted to endorse the $3.5 billion Metro bond that will appear on the November ballot.
