LONG BEACH (CBS) — Thousands of Cal State University teachers, librarians, counselors and coaches could soon walk off the job.

The California Faculty Association announced Wednesday that the 24,000 CSU employees it represents have voted to authorize a strike.

The union, which has been negotiating contracts with CSU leaders for 22 months, will now decide whether to implement two-day rolling strikes on all 23 CSU campuses.

The strikes would be the largest among faculty in the history of the United States.
