Loeb has held the post since 2008. The vote came during the last session of the IATSE’s 67th Quadrennial Convention at the Boston Sheraton Hotel with 800 delegates from 400 locals attending.
Loeb and his slate, including General Secretary-Treasurer James Wood, ran unopposed.
The union said Loeb has overseen organizing drives, increased training, emphasized the importance of safer working conditions, supported labor-friendly political candidates and opened lines of communication through social media.
Loeb succeeded longtime IATSE topper Thomas C. Short five years ago, after the latter stepped down with a year remaining on a four-year term. Loeb had been division director of motion picture and television production for the previous decade.
Loeb has also improved coordination with the Intl. Brotherhood of Teamsters and craft unions. The 2011-12 round of negotiations marked the first time the unions had jointly negotiated with the West Coast locals of IATSE on a three-year healthcare deal, which expires in 2015.
