The union representing Windsor's garbage and recycling collection workers is asking city council to put off a decision on contracting out those services when it meets Monday night.

A report by city staff recommends collection be contracted out to Toronto-based Turtle Island Recycling Corp., estimating savings of nearly $9-million over seven years.

But Jim Wood,  president of Canadian Union of Public Employees Local 82 which represents the 50 city workers now doing the job, says the union still hasn't received all the information from the city to review the numbers in that report.

He says the issue is complicated and his executive needs more time to review it.

Meanwhile, Coun. Bill Marra says the potential savings identified in the report are too big to ignore.

The city says the workers would not lose their jobs but would be placed in other positions or allowed to retire.

About 20 delegations are expected to make presentations to council on Monday night.

Windsor's garbage collection services made headlines last year over a 15-week job action that brought collection and other services to a standstill.
