JOHANNESBURG - The National Union of Mineworkers (NUM) says workers at Eskom's Medupi Power Station could down tools again next week.

The threat is adding strain to the power utility and could derail its December deadline to generate power.

Public Enterprises Minister Malusi Gigaba has warned heads will roll if they don't meet the deadline.

On Thursday construction at the plant came to a halt as workers embarked on a short work stoppage.

The NUM'S spokesperson Lesiba Seshoka says, "Next week, there may be a protest … over issues related to disciplinary measures, because there are some who were not disciplined when they protested."
