I would very much appreciate your advice on the following: I have entered into an Employment Contract about a year ago which stipulates that the offer was made under the condition that I'm not affected by any injury, disease, etc., i.e. any condition that will prevent me from performing my duties. Question #1: Under Australian labour law, is this at all legal? It said further that I would need to speak to HR in case I wasn't sure, so that the company could make a proper assessment via medical examination, etc. Question #2: Would they have had the right to request this? The unfortunate situation is that I have recently been diagnosed with a chronic disease requiring treatment which may temporarily affect my performance. As part of the disease management plan and as per advice from the physician, it is best to disclose my condition to my employer which I am planning to do asap. Question #3: From a legal perspective and based on Australian labour law, what is the worst case scenario that might occur? Is the company at all in a position to breach their contractual obligations, enter into dispute, etc.? For clarification purposes, my employer has 457 visa sponsorship for a period of 4 years. Looking forward to getting some advise in these rather delicate circumstances. Thank you for your support in advance!
