The measure, which is backed by Mayor Todd Gloria, would permit the city to recognize project labor agreements covering multiple contractors and unions in order to receive federal funds. These agreements were banned in 2012 by an earlier ballot measure that sought to exclude unions to lower construction costs.
Opponents say the measure would keep out 80% of the construction industry that is non-union and shut out many minority-owned firms.
The effect “is discriminatory in nature,” according to the National Black Contractors Association, because it would “give a monopoly to around 20% of San Diego’s construction workforce.”
Association President Abdur Rahim Hameed appeared with civil rights leader Shane Harris and other community leaders at a rally Thursday to urge voters to reject Measure D.
