Cenovus needs the Deep Basin and WCBU staff to works the assets they just purchased as they didn't have positions in ANY of these non Oilsands assets prior to the purchase.
Unless they are grossly overstaffed in their existing Oilsands assets, I don't see how they can get rid of the COP staff currently working Deep Basin Assets.
Although they can easily remove the middle management layer cake that somehow avoided the last 4 rounds of layoffs.
