Does Eskom give their workers lunch money or is just assumptions? Could it not be S&T claims? My employer doesn't give me lunch money but we do claim for food when we go for training, when we are working away from home and other such instances.
So yes, sometimes salaried employees do get food at the employer's expense for practical reasons, without knowing the background to the food costs it's hard to make an informed comment, all we can agree on is that the costs should be managed and not go out of hand.
