Just before his speech on Thursday in Brandon, Michelle Gawronsky, president of the Manitoba Government Employees Union, stood before the crowd and challenged the premier to get new contracts for thousands of government workers.
She said 25,000 union members don't have a contract after a year at the bargaining table.
Gawronsky said it's time for a fair and reasonable offer so a deal can get done.
Selinger said after his speech that his government is always in favour of fair and reasonable collective bargaining.
About 500 delegates are attending the convention which runs until Sunday at the Keystone Centre.
