Far from over. The government won't force the union to vote on Canada Post's "Final Offer" from last week, and won't force Canada Post to agree to the union's request for "fair and binding arbitration".
So I think a full-blown strike is inevitable, and the government won't do anything to stop it, except perhaps to allow a full strike to run for 4 or more weeks, and then force the workers back to work again for another few months or so.
Taking us back to the same stalemate.
In other words, kicking the can down the road...
