Thx everyone
i always obeyed the conditions that was attached with my visa i did my best
But health comes first i even told to my boss i am human being not a robot machine . We had short staff problem from almost 4 months i said how long more i have to work like an animal
When i had enough without thinking anything i told him i can't work any extra and he gave to termination letter
Now its upto DIBP what they will decide
