Yeah if the CIRB doesn't get appealed and resolved quickly (before the end of the year I'd guess) unions would have ample reason to continue picketing while tabling an agreement, if they so chose.
Then, on Wednesday afternoon, the ILWU unceremoniously, and without explanation, withdrew their new 72-hour notice to resume strike action by Saturday.
If that's the case though, I have to admit folding without even making them go through with the legislation is pretty sad. That sends a terrible message to companies and the government. Corruption or not, it's just another bad outcome from this whole debacle.
