An electrical services company has been accused of attempting to bribe its workers to vote Liberal, with a promise of $100 if the Coalition wins on Saturday.

Western Sydney-based HMP Electrical has been referred to the Australian Electoral Commission after a worker took exception to an apparent inducement to vote Liberal.

A text message sent to staff, obtained by Fairfax Media, said: “Hi Guys – As you may or may not be aware, the federal election is on Saturday, 7th of September 2013. Eddie has asked me to remind you to VOTE and to let you know that if the Liberal Government win you will all receive a $100 GIFT as employees of HMP Electrical Services. Aren't we lucky to live in a democratic country! Kindest regards, Nesska (for Eddie)”

The Eddie referred to is HMP owner Edmond Hajar, who runs the Northmead-based business comprising some 20 employees.

The Electrical Trades Union took a complaint to the Electoral Commission on Friday after receiving legal advice that the offer of $100 could constitute a bribe under section 326 of the Commonwealth Electoral Act.
