How did you spend your summer vacation?If you ask that of the Manteca Unified support staff — from maintenance crews to those that labor at the district office tackling everything from curriculum, budgeting, technology, transportation, and operations to nutritional services — the answer is working to make sure everything is ready for 3,000 employees and 23,500 students to hit the ground running when the new school year starts Aug. 6.“Operations and business keep busy the entire summer,” noted Superintendent Jason Messer.The task for those working at the district’s campuses is obvious. It is time for deep cleaning and doing routine maintenance repairs and sprucing up campuses that weathered 23,500 young people for 180 days.But the effort at the district office may not be as apparent although in many ways their workload increases wrapping up one school year and starting another. It’s much like what teachers and site administrators do but due to the nature of the work it doesn’t stop.That said the district complex shuts down the first two weeks of July in a bid to reduce energy costs and such.
