CHICAGO – There’s still nearly a year and a half left on the Chicago Teachers Union’s current contract, but the radical labor group is already hinting that another teachers’ strike could be on the horizon for 2015.

Chicago Catalyst reports that CTU President Karen Lewis “laughed when asked whether the union plans to terminate the contract in June 2015 rather than renewing it for another year.”

Lewis said the union is unlikely to agree to a fourth year, which would reignite contract talks between the union and the city.

CTU delegate Jay Rau told Chicago Catalyst that the same tensions that led to 2012’s historic walkout could be repeated next year. If so, that could mean Chicago families can expect another long, hot summer of labor strife in 2015.

That certainly seems possible, given that the teachers union and other city labor groups are already in fight mode. The unionists are rallying against a plan by Chicago leaders to ask union workers for financial concessions to help close the city’s serious pension deficit, the Catalyst reports.

Last month, CTU members voted to form an independent political organization to help union teachers flex their political muscles on a variety of issues in 2015.

“I think we’re just going to promote very important popular issues,” CTU official Jackson Potter said, according to DNAInfo.com. “But 2015 is on. It’s definitely gonna be an election season we’re interested in working with others around.”

There’s one thing that might take the wind out of CTU’s sails: The election of Republican gubernatorial candidate Bruce Rauner.

If the fiscally conservative, anti-union Rauner somehow becomes Illinois’ next governor, CTU members might decide to renew their current contract for another year, rather than pushing for a “stronger” one, according to Chicago Catalyst.

Presumably, that’s because city leaders may be emboldened by the anti-union governor into taking a harder line with the union in contract talks.
