A rescued galah Crackers, unable to fly, found a new home when it was saved by Gregg Dunshea in Bundaberg regional Queensland. 

But 'Crackers' was killed last year when he was run over by a worker. Crackers owner decided to sack the worker who was behind the wheel. 

The worker who was sacked has since taken Gregg to fair work over unfair dismissal. 

Michael Byrnes Human Relations expert and Partner at Swaab Lawyers talks to John Stanley about what  qualifies for unfair dismissal and how should employees and workers  deal with these workplace disputes.
