The Los Angeles Times announced Monday it would reduce up to 5 percent of its workforce through voluntary buyouts, elimination of open positions and a voluntary four-day work week at reduced pay. In a memo to employees, Times Publisher David Hiller said the cuts are necessary to keep staffing in line with revenue, which is falling in the core print business. The cuts will come across all departments. Employees have until May 14 to submit an application to consider being part of the voluntary buyouts. Employers who are chosen receive one week’s salary for every six months they have worked for the company. The Times operates Times Community Newspapers, which publishes the Glendale News-Press, Burbank Leader and La Canada Sun newspapers.
