Opposition United Party for National Development President Hakainde Hichilema has written to President Michael Sata over the plight of striking nurses.
Meanwhile, the nurses have refused to budge until their demands are met by the government who have been playing down the impact of the strike.
In his letter to President Sata, Hichilema called for the speedy address to the impasse that has paralyzed the country's highest referral health centre.
"We are concerned with the stand off between your government and nurses and midwives. In typical fashion your government has negated its earlier pledge to increase their salaries by 200 percent and have effected increases of up to 4% only," Hichilema's letter reads in part.
Hichilema said contrary to claims that the pharmacy was open and that nurses had reported for work the reality was different.
The strike action has spiralled out of hand with workers continuing their strike.
Government had recently announced that they had given civil servants a healthy increase that stretched up to 200 percent in some instances but the reality has caused upheavals in the health sector where nurses and midwives have downed tools saying they were duped.
