About 2,500 Caterpillar Inc. employees are temporarily out of work without pay while the company shuts down some plants as part of an effort to bring production in line with demand.

About 1,500 of the affected employees work at Caterpillar’s Mossville truck engine plant and 977 work at the track-type tractor facility in East Peoria. Divisions at both plants are shut down this week but are expected to begin production again next week.

Caterpillar announced last week that demand for its products in North America is expected to decline this year.
