The agitated interns have been protesting and camping outside Afya House since Monday expressing frustrations over years of waiting for their official posting after completing their studies.
KUCO Secretary General George Gibore called off the strike, which had lasted for more than three months after signing the agreement.
The union had planned to camp at Afya House until all medical interns were posted to health facilities nationwide in line with the 2017 Collective Bargaining Agreement (CBA).
