The simple answer is “NO”.
If you have a work-related injury or illness and you can’t work in your usual job, your employer cannot use this as a reason to dismiss, sack or fire you within 12 months of the date of your injury or illness.
If you are fit to return to your usual job within 12 months of your injury or illness, you may ask your employer to return to your usual position. Your employer may require you to provide a medical certificate proving your fitness to return to work.
