Zinaida is an activist of the Independent Trade Union of Radio and Electronics Workers (REP). Since 2000 she headed the union's primary organisation at the Tsvetotron plant.
On 25 October 2020, Zinaida was detained at a protest in Brest. Right after the administrative court hearing she was detained again, this time as a suspect in a criminal case of violence against a police officer. The outcome of that case is unknown.
On 25 March 2022, security officers searched Zinaida's home and the union office and detained her. The charges were based on recordings from wiretapping that had earlier been installed on her as a union activist.
In May 2022, Zinaida was found guilty in a criminal case of insulting Lukashenko and sentenced to imprisonment.
Released in January 2024 after serving her full sentence.
