United Teachers Los Angeles officers will camp out in an RV at Los Angeles Unified headquarters starting today to protest payroll glitches that have led to over- and underpayments for thousands of employees since February. The camp-out is the latest effort by the union to step up pressure against the district to resolve the problems. Superintendent David Brewer III has said the district can fix all the problems by next July. “July 2008 is way too late,” UTLA President A.J. Duffy said. “We’re going to continue to support our teachers and highlight the problems for the community. “They have sent out so many contradictory messages that we’re not sure what’s accurate and what’s not and what’s true and what’s not.” Reed said the language of the union’s collective-bargaining agreement precludes the union from engaging in work slowdowns including walkouts. Any legal action against the union would require school board action, he said. UTLA has already called for teachers to boycott after-school faculty meetings. But Reed said he hopes the teachers union will work with the district to resolve the problems. “We don’t know if (walkouts are) going to happen, but it is a situation where we believe that the instructional programs and operation of our schools are going to be impacted,” Reed said. “Right now we’re hoping to de-escalate with meaningful conversations.” [email protected] (818) 713-3722160Want local news?Sign up for the Localist and stay informed Something went wrong.

Brewer announced Thursday morning that he expects 5,000 certificated employees, including teachers, to be affected by problems with today’s paychecks, roughly the same number as the last pay cycle. Of those, about 300 will be underpaid, and the district has already contacted those to give them emergency checks. The district has also extended customer-service hours to the weekend to help those with paycheck problems. But amid the increasing tension over the issue, LAUSD general counsel Kevin Reed has issued a warning that UTLA should not be encouraging teacher walkouts to protest the problems. Duffy had threatened walkouts while testifying about the payroll problems in a Senate committee hearing last week.
