I don't think anybody who runs a corporation is of the belief that they can control every single thing that goes on with their employees. Would that it existed.
I will say that I think the challenge is both in terms of policy and then in terms of execution of that policy. Some of the things that have been pointed out are actually by Canada Post's design, so the issue is with management for not creating those processes, or perhaps with government for not creating the processes above the corporation that would provide avenues for appeal, etc. Then, there are also problems on the execution end, where the employee may be overzealous or misapplying a particular policy, with little recourse for private sector users.
