 During the recession years (December 2007 – June 2009), the CSU lost 1/3 of its revenue – roughly $1 billion – and 4,000 employees.With the state's reinvestment in higher education, the CSU is restoring its employee ranks and currently employs a record number of instructional faculty.Between 2010 and 2015, the number of CSU faculty increased by 3,500, but the number of tenure track faculty declined by 150, leaving the CSU system with its lowest percentage of tenure track faculty (39%) in the schools' history.
