I feel sorry for what you are going through. It is a shame that an employer thinks that they are able to treat employees like this. I can not understand how ignorant they are regarding super and work cover. Take the advice of many on this forum:
1) Do not allow yourself to be bullied and treated like a drone
2) Be fully prepared to walk and find a decent employer
Maybe, just maybe if they had any business sense they would realise that a happy employee leads to happy customers and a happy customer leads to profits. But they seem to have the formula back the front. Oh well, that is their choice and their loss!
