There was no offer, they were ordered back to work by the government with the government imposing a temporary contract that ends in May. There's been zero movement on the contract; current pay, in CanadianPesos is $21.80CAD, that's $15.52 in Freedom Bills. Their pay has been stagnant since 2021. After seven years of work, you can expect to reach the top of their pay tables at 29.18CAD, that converts to just $20.78USD.
Nobody cares, I'm shocked honestly there still is a mail service up there. Tim Hortons pays more.
