Aw shit. No, its not. This was a negotiated termination, not a sacking. A sacking is where the employee can unilaterally terminate as a result of breach of an essential contract term by the employee. We sought to end Griffin's contract early, without him giving cause, hence negotiations were required.
Agreements will typically provide for a defined payment if the employer terminates for no cause. In the NRL, typically this would be minimum 12 months given the time required to secure one of the limited opportunities. If Hook pushed for payout in excess of the contracted amount (& given the circumstances the club had no choice but to negotiate), the club may have sought its own conditions, including full payout but Hook not to coach NRL for a time.
This is just 1 scenario. Who knows what the negotiations were or where they landed.
