The Colorado Community College System is warning several dozen online instructors that their jobs are at risk if they do not live in Colorado.

Southwest Community College, with locations in Mancos and Durango, is part of the system.

The Denver Post reports that college system officials say they are “phasing out” teachers who live outside the state. They say it has become too expensive and difficult to manage all the teachers while adhering to the various education and labor laws that apply to each of their home states.

It is unclear the exact number of teachers that will be affected by the change. But in August, officials estimated there were about 250 out-of-state employees across the 13-college organization.

The system has about 10,000 employees, not including student workers, and enrolls more than 151,000 students.
