MORE than 400 lecturers and researchers at Zambia’s largest state-run university have gone on an indefinite strike in protest against the non-payment of their January salaries, a senior union official said on Thursday. University of Zambia lecturers and researchers union vice-president Douglas Syakalima, said, that academic staff at the institution decided to strike late on Wednesday because of the government’s failure to pay their salaries on time. The government has not yet responded to the latest work stoppage at the country’s main university, which is coming on the heels of a doctors strike that crippled hospitals in the country.
