The workers are demanding salary increases, productivity bonuses, and a general restructuring.

The Central Bank of Brazil has postponed, for the second time, the release of a highly followed economists’ survey, as employees protest to demand a wage increase. The employees plan to strike until Thursday, escalating a months-long labor dispute with President Luiz Inácio Lula da Silva’s government.

As a result, the institution’s Focus survey, which incorporates estimates from over 100 analysts on data such as inflation and the benchmark interest rate, will now be published on Thursday instead of Monday, its normal release date.

The dispute at the Central Bank of Brazil has intensified in recent weeks, also delaying other reports containing data on foreign direct investment, domestic loans, and fiscal accounts. The central bank staff was excluded from the salary increases granted by Lula’s government to other officials, and in May, they began a strike demanding a 36% salary increase and other benefits.

Some employees warned of “greater risks” to the bank’s mission in a letter sent to the board on Monday. “It is essential that the board reinforce its actions,” wrote over 40 department heads of the central bank.
