A last-ditch effort to avoid another postal worker strike.

Canada Post proposing parcel delivery seven days a week in their latest offers to the Canadian Union of Postal Workers.

In a release, the company says the offers also include a 13 percent wage increase over four years.

CUPW president Jan Simpson says their negotiating committee will carefully review the documents.

Workers could be off the job as of Friday if a new deal is not reached.

A strike late last year halted mail delivery into the holiday season before government ordered members back to work.
