I recently found an advertisement for my job at a higher wage than I actually get, before I confront my employee I want to get some information. I have been with the company 12 years and have never been on maternity before, I plan on taking 9-12 months off all together but in the advert there is no mention of this being maternity cover. I know that when I come back they have to offer me a job at the same wage that I am receiving at the moment but I am so angry that they can offer a higher wage then I already get?
