She said Imvula got an interdict in the Labour Court against them. "This is viewed in a serious light by the company," she wrote.The main concern of employees appears to be their working conditions.Winter"It's winter now. It's cold and raining, but some employees are placed where there are no guardrooms or shelter, no clean water, toilets or electricity," said one of the workers.One worker, they said, is using a toilet as a guardroom in Durbanville where he is guarding City Council premises.Another worker, stationed in Khayelitsha where the City is developing land for a sportsfield, said, "I travel a long distance to relieve myself at a nearby site … I was warned that I would be dismissed if I leave my work station to relieve myself."Workers also say their wages are very low. One employee, who has worked for iMvula for 10 years, said there are three grades: grade A employees are paid R5 200 a month for 12 hours a day, six days a week; grade B employees work 12 hours a day, six days a week and get R4 800 per month; grade C employees work 12 hours per day, three days a week and are paid R2 800 per month.Imvula would not comment on the allegations.Mayoral Committee Member for Assets and Facilities Management Councillor Stuart Diamond said that iMvula is contractually bound to comply with the tender document which describes minimum conditions of work for employees.

We gathered outside to hand over a petition. But to our surprise the company called armed security for us… We saw the security taking big guns and pointing them towards us."Another employee said, "Management said they suspended us because we embarked on an unprotected strike. But we intended to go to our sites after we got answers and everyone reported for duty as usual. All we need is feedback."According to the suspension, workers are not allowed on iMvula's property or that of its clients. "You may not contact any staff member during the term of suspension without written permission of the director of Human Resources, which permission will not unreasonably be withheld."The Democratic Union of Security Workers (DUSWO) represents the employees. General Secretary Mzwandile Jackson Mabongo also would not comment.
