Fresno Nurses Strike?

The Fresno Bee reports:
The California Nurses Association, which represents about 300 nurses at University Medical Center, delivered the 10-day strike notice to hospital officials late Friday. The advance notification, required by law, was delivered not long after contract negotiations between the two sides concluded earlier in the day. The two sides have been trying to come to a contract agreement for more than a year.
