The City of Windsor's inside and outside workers could have a new collective agreement tonight.

Their CUPE bargaining committee for locals locals 543 and 82 recommends workers vote in favour of tentative four-year contracts

The key issue at the bargaining table was the city's insistence on placing a cap on sick leave days. The city said it is trying to keep rising costs in line.

More details on the contract and negotiations will be revealed at the ratification meetings Monday night.

"I'm not going to get into a discussion right now. Ultimately, it's a decision that needs to be made by our members. It's only fair to them that they have an opportunity to look at them first," said Kevin Wilson, a CUPE spokesperson.

The current contracts for more than 1,000 inside and outside employees expire at the end of 2012. In 2009, they went on strike for more than 100 days before a new contract was ratified.

A conciliator helped the city and CUPE bargainers reach the tentative agreement on Friday afternoon. Mayor Eddie Francis was quick to make an announcement.

"I think it's in the interest of the corporation, the interest of the membership and in the interest of the community that the agreement reached is ratified," Francis said.

The union bargaining committees are recommending workers accept the tentative agreements Monday night.
