The man suspended by his union bosses because he was standing as an Act candidate has been sacked.
Shawn Tan is considering taking legal action against the Engineering, Printing and Manufacturing Union.
His fate was decided at a meeting last night after mediation on Friday failed to resolve
issues.
Mr Tan, who worked as an organiser at the Labour-affiliated call centre, was suspended on August 18 when it was revealed that he would be standing as a candidate for Act, which the union says has a different philosophical persuasion.
The EPMU said Mr Tan had not sought permission to stand and accused him of using a work computer to send Act emails during work time.
"We tried to mitigate the outcome," Mr Tan told the Herald last night.
"I would be prepared to go back if the conditions were right, for example if the EPMU could guarantee my safety, that I wouldn't go back and face barrage or ridicule or the disparity of treatment. They couldn't guarantee that and said I was asking too much. I was pretty disgusted by that actually."
EPMU national secretary Andrew Little said Mr Tan was fired over contractual reasons.
"The decision is about his employment obligations, it's not about his political affiliations ... he has employment obligations to the union and he has chosen not to abide by those.
"Added to that he has chosen to attack the union publicly."
Mr Tan said he would liaise with his lawyer today about legal action.
