Workers and Wall Street were anxiously awaiting the news out of General Motors Corp.’s annual meeting this morning, with expectations that the beleaguered automaker will announce more restructuring measures that could further reduce the number of jobs and even idle factories in an attempt to improve its sales and financial results.

For workers at GM’s truck plants, that has meant wondering whether there would still be jobs to report to following the next round of change.

In its announcement today, the automaker is expected to give those plans more clarity by announcing plans to increase the production of small and midsize cars at its assembly plants in Orion Township and Lordstown, Ohio, even as it takes steps to further reduce production at some GM truck plants.

Workers at Orion Township and Lordstown are hoping for increased car production, added shifts and the promise of new models.

Analysts and economists have said they wouldn’t be surprised to see cuts at a Michigan plant — in Flint or Pontiac — or those in Janesville, Wis., or Moraine, Ohio.

GM is not commenting on the planned announcements, though spokesman Tom Wilkinson has said that the company has no big salaried layoffs in the works.
