James Ruh, co-chair of the company's board, said he supported unionization for the dancers. "It would be helpful as a way to correct a lack of uniformity," he said. "If they unionize, we'll go forward. I'm not sure there's a downside to this."

Colorado Ballet was recently disrupted by the abrupt departure of artistic director Martin Fredmann, who rejected the board's offer of an emeritus position and resigned instead.
