Tony Stack interim CEO of English School District

The Newfoundland and Labrador English School District has promoted one of its executives to the main job of running the board, after the former CEO departed for a new job at the teachers' union.

Tony Stack will serve as interim chief executive officer and director of education, the district's board of trustees announced Wednesday.

The appointment is effective immediately.

Stack has worked as a teacher and a principal at St. Peter's Junior High School in Mount Pearl, and most recently as associate director of programs for the school district.

He also served for decades in the Canadian military, retiring from the Canadian Forces Army Reserve in 2016 with the rank of Brigadier-General.

Stack replaces Darrin Pike, who resigned to take a new job with the Newfoundland and Labrador Teachers' Association, a move that sparked concern by the provincial education minister about perceived conflict of interest.

Pike's last day at the school district was Tuesday.
