He was arrested on September 21, 2021, as a defendant in a criminal investigation into 'high treason' (Article 356 of the Criminal Code) involving several employees of the Belarusian factories who supported local strikes in 2020 and were members of the Rabochy Rukh labor rights group. On September 21, 2021, that initiative was labeled as an "extremist" one, which entailed arrests of workers across the country. Besides, Siarhei Dziuba was charged under Part 3 of Article 361-1 of the Criminal Code ('Creation of an extremist formation and participation in it').

He was placed in the KGB remand prison in Minsk and then transferred to remand prison #3 in Homieĺ.

On November 9, 2022, the Homieĺ Regional Court began the trial of the Rabochy Rukh case involving ten political prisoners. On the second day of the trial, all the defendants refused to admit their guilt in high treason and the creation of an extremist formation. All the defendants refused to testify at the trial. From December 27, the trial was held behind closed doors until the verdict was passed, although, before that, it had been held in open mode.

On February 17, 2023, the court delivered the verdict. Judge Aliaksandr Piskunou found Siarhei Dziuba guilty under the above articles and sentenced him to 12 years of imprisonment in a medium-security penal colony.
