Bill Shorten's position as Australian Opposition Leader is looking increasingly shaky after another round of harmful revelations about deals struck by the trade union he ran before entering Parliament.
The Labor leader's political judgment is also being questioned amid a dreadful week that has seen him forced to beat an embarrassing retreat over people-smuggler payments, and that left his party the sole opponent of pension changes designed to benefit the less well-off.
And as Shorten's popularity ratings plummet to an all-time low, the Sydney Morning Herald has called on him to "consider his future", saying his "continued tenure [as leader] is damaging his party and the interests of the people he claims to represent".
The revelations relate to his lengthy service as Victorian state secretary, then national secretary, of the influential Australian Workers Union (AWU), and to large sums paid to the union by companies after he struck deals perceived as favourable to employers and disadvantageous to workers.
According to Fairfax Media yesterday, AWU Victoria received payments totalling nearly A$300,000 ($335,735) from a construction company, Thiess John Holland, following an agreement in 2005 to cut wages and conditions for workers on a major Melbourne road project, the A$2.5 billion East Link tollway.
