There’s a lot of jockeying going on over who will succeed local trade union boss Neil Struthers, but reports of his departure to Sacramento may be premature. In October, the state Building and Construction Trades Council will meet in Santa Monica and vote in a successor to its chief of 20 years, Robert Balgenorth. The two presumed candidates for the position: Struthers, who’s married to Assemblymember Nora Campos, and Robbie Hunter of the Los Angeles/Orange Counties chapter.
