I worked at an expocrete plant in Acheson, AB for two years. Production equipment was frustrating to deal with, it was always in some sort of malfunctioning state or had to be limped along with constant worker intervention. Management never seemed to listen to our requests for working equipment, but they were keen to micro manage. I watched a supervisor break lock outs on the daily, it was reported and nothing ever came of it.
Management, supervisors, broken equipment, lack of HR or Safety.
