Retirement benefits can be expensive. I know of one retiree who paid $200 a month for himself and his wife. Ontario nurses don't even have a retirement benefits plan.
Before the tenative agreement, there was a proposal by Canada Post to increase retiree benefits premiums by 30%. With the tentative agreement, this rollback and 15 other negative suggestions are off the table.
With 10,000 senior workers retiring over the next four years including me, the above is a big gain for us.
