The Alberta Labour Relations Board has made a ruling in a case filed by the union that represents zoo employees.

CUPE Local 37 filed a case with the board arguing that the Zoo Society and City of Calgary constitute a common employer and the board agreed.

"This issue was about cutting wages and working conditions to employees who have worked at the Zoo for years," said CUPE 37 President Don Monroe in a release. "The Society admitted as much at the hearing, and we're grateful the board wouldn't allow it."

The Zoo Society says it does not have a place at the bargaining table and was proposing to replace vacant positions, created through attrition, with other employees.

Monroe says that now that the Labour Board decision is behind them, he hopes the union, the Zoo, and the City can concentrate on building their relationships and continuing to provide a world class Zoo to the people of Calgary.

The City of Calgary did not take a position in the proceedings.

The Zoo Society says it sees the decision as a positive step forward and they are looking forward to working with the city.
