Pretty tough to sack somebody outright for having a depression diagnosis. Especially from only two sources and only one saying little chance of recovery, whilst the other just advising to take time off until recovered. It would be important if the disorder should be related to the stress of the position and if so it would be directly related to work and workcover and require the company to assist in rehabilitation of the individual, not to turf them out on their ear. I would have thought it would have had to go to at least a medical panel before termination occurred.
