Stun grenades were used in Parliament today‚ for the second time in a month‚ as police tried to disperse striking National Education‚ Health and Allied Workers’ Union (Nehawu) workers. Several stun grenades were used to disperse workers who had gathered on the steps of Parliament's National Council of Provinces (NCOP) building after having disrupted several committees.Riot police were called onto the precinct and were seen dragging at least two workers away.Politicians from the ANC‚ DA and the UDM however negotiated between the workers and the Speaker's office in a bid to end the impasse.The UDM's Nqabayomzi Kwankwa‚ who acted as a go-between between the workers and the Speakers office‚ requested workers to continue their protest peacefully and offered to try to secure the release of those who had been arrested.Just before 2pm‚ the ANC chief whip Doris Dlakude told workers that she had negotiated for the release of the worker who had been arrested and urged the workers to allow the sitting of the house‚ scheduled for 3pm‚ and committee work to go ahead."I've played my part‚ I am begging you to allow the afternoon sitting without interruption."The DA's Mmusi Maimane‚ who also came to negotiate‚ said that while they could not become involved in the wage negotiations‚ "we don't want anyone else to be arrested or injured".Parliamentary researcher Sonwabile Ngxiza was released to a heroes welcome as workers chanted and cheered and carried him out of the precinct on their shoulders. He said he had been held in the Good Hope Chamber. He sustained some cuts and scrapes while being dragged from the steps of the NCOP. He also sustained a bruise on his head.A woman who said her foot had been injured on the steps of the NCOP was seen being wheeled away in a wheelchair.The striking workers will meet with Parliamentary management at 5.30 today.- TMG Parliamentary Bureau..
