A problem faced by Unicamp, and other public universities in Brazil, is the high dependency on economic conditions, that directly impact tax earnings, while most of the expenses, payroll specially, are indexed to inflation. While not as critical as in similar universities (at the University of São Paulo payroll accounted for over 106% of the total funding available in 2014), Unicamp currently faces a funding crisis, with total funding expected to decrease in real terms while payroll, which takes around 85% of total university funding, is expected to increase in line with inflation. This situation is aggravated by the long-running trend of raising staff salaries above inflation as a response to the annual strikes led by the workers' union, STU.
