Stricter hiring policies in San Diego have left 150 city positions unfilled and limited the number of newly hired workers since mid-December to 14 jobs that do not require taxpayer money. This has led to noticeable reductions in services such as restroom cleaning at city beaches, maintenance at city pools, and tree trimming, road striping and library youth services. Rolando Charvel, the city’s chief financial officer and Mayor Todd Gloria’�s top budget official, warned that many of the unfilled positions could remain vacant for months due to a projected $120 million deficit for the new fiscal year. The new policy also includes a suspension of most overtime pay, restrictions on expenses for training and a deep analysis of outside contracts.
