Limpopo Premier Cassel Mathale has filed papers in the Johannesburg Labour Court in a bid to stop government employees from picketing outside his office, according to a report on Monday.
In a court document, Mathale said the demonstrations disrupted the working environment, The Star newspaper reported.
"The picketing inconveniences members of the public, intimidates employees who do not participate in it, and also inconveniences those who wish to continue with their work," his affidavit said.
Workers affiliated to the National Education, Health and Allied Workers' Union, (Nehawu) had been holding lunchtime demonstrations since February outside the premier's office in Polokwane.
Workers complained about non-payment of performance bonuses, the transfer of employees without consent, restructuring without consultation and alleged corruption and intimidation by senior management.
Mathale had requested the court to hear the matter urgently on Wednesday at 10am in Johannesburg.
The union and 12 employees are mentioned as respondents.
