A "serious public transport crisis" is facing people living in the eThekwini municipality, the Congress of SA Trade Unions said on Tuesday.

"As Cosatu we are quite concerned and worried about the serious public transport crisis facing our people within the eThekwini municipality," provincial secretary Zet Luzipho told reporters in Durban.

"The issue of Durban transport remains unresolved and we are quite worried about the silence of the municipality."

In 2009, the KwaZulu-Natal transport department appointed a new bus operator, Transnat Africa, whose contract expired in October last year.

"What make matters worse is the unreliability of the taxi industry due to their running legal battles with the municipality, in particular the metro police."

Luzipho said workers within the municipality were facing difficulties with their employers.

"Many workers are continuously subjected to disciplinary warnings from their employer," he claimed.

"At worse this has also some serious implications for the education system," he said, referring to scholar transport.

Luzipho said the union federation would request a meeting with city officials.

The municipality was not immediately available for comment.
