Shoreline Unified School District’s administration is hoping to put last Monday’s apparent strike—in which 20 of the district’s 50 classified staff phoned in sick—in the rearview, but it has yet to make any headway with the California School Employees Association, the union that represents 48 of the 50 classified staff.

Markey Lees, the union representative, did not respond to requests for comment, but last week said the one-day strike was not authorized by the union.
