How about making use of company resources to mail personal correspondence and get sacked?
Dismissal from NUS
In 1993, a few months after Chee joined the SDP, he was dismissed from NUS by the Head of the Psychology Department, S. Vasoo, who was also a PAP MP at the time, for allegedly using research funds to send his wife's doctoral thesis to the United States and making false transport claims. Chee denied that he had misused university funds and claimed that he was the victim of a political vendetta.
He staged a five-day hunger strike to protest his sacking.
