I have been at my company for 16 years as a receptionist. I have become a very efficient all rounder. A month ago our accounts assistant retired. I was offered his duties that would be added to my existing portfolio for a R2000 increase. I stated that the offer was not feasible for added duties. They asked what I would consider feasible and I said R6000 increase. They came back to me saying that the responsibilities will be split among the branches and the manager himself is handling the remainder of duties. Now according to HR, the company is looking for a new accounts assistant. Is this right? Can they do that without even negotiating a package with me? Do I have any ground to stand on and take this up?
