On 27 February, the National Union of Higher Education Teachers (SINPES) in Angola started a strike demanding better working conditions and fulfillment of the promises made by the government. Since the beginning of the strike, union leaders – including general secretary Eduardo Peres Alberto- and their relatives have been the target of death threats. On 25 April, Eduardo Peres Alberto’s daughter was attacked on the street by unidentified men who used a toxic chemical. The Angolan authorities must promptly, thoroughly, impartially, independently, transparently, and effectively investigate both the attack and death threats and ensure the Union leaders’ right to unionize and strike is protected.
