The Engineering, Printing & Manufacturing Union has sacked an employee who wanted to stand for Parliament as an ACT Party candidate.
The union says it sacked Shawn Tan after deciding his actions had irrevocably damaged their employment relationship.
EPMU national secretary Andrew Little says the issue of Mr Tan's candidacy was never about his political affiliations, but about his obligations to the union.
Mr Tan was suspended on full pay earlier.
The EPMU says two other employees have sought approval to stand for public office this year: one was declined and the other approved.
