Some frayed nerves at the end of the annual Canada Post meeting in Ottawa today.

The Canadian Union of Postal Workers is frustrated that the Crown corporation refused to lay out its calculations – on the cost of the union’s latest contract proposal.

Canada Post has estimated the union’s demands on pensions and pay equity would cost one-billion dollars.

A frustrated CUP-W president Mike Palecek says they’ve repeatedly asked Canada Post officials to explain how they arrived at that number –  but have run into a wall of silence.

Refusing to take questions about negotiations, Canada Post officials focused on the volatility of  the worker’s pension plan –  with the solvency deficit now reaching 8.1-billion dollars.
