TSS Johannesburg, Slavery

Good day my leader's Mr Benjie Johannesburg area manager he's running T.S.S. like the fly by night.Because people are not offing he's forcing them to cover for the new site,But he's not paying them over time money he is saying to them if they don't want to work they must go, Because he's paying them lot of money,Especially Reaction, supervision and TRT,In their payslip the money was increased but he told the owner of the company they don't deserve that salary.Even when they are involved in accident they don't pay access fee, But they pay the amount that has fixed the car and I believe those car's have insurance.He doesn't care about them but all he Care's about is he's salary and saving money for the company.He doesn't even think about fatigue.Because those people are working like slave's.Please help us guy's please!!!!He even wanted them to contribute for the December braai on that cent he's paying them, can anyone help them.
