Yaw joined the WP in June 2001 and joined the
Central Executive Committee (CEC) at some point in time. He remained in the CEC until 7 February 2012, when he suddenly resigned from the post of Treasurer. In the
2006 general election, Yaw led the WP team contesting
Ang Mo Kio Group Representation Constituency (GRC), which was anchored by then-Prime Minister
Lee Hsien Loong. Made up largely of young, first-time candidates under the age of 35, the team was dubbed the "suicide squad" by the media, and then-chair of the governing
People's Action Party (PAP),
Lim Boon Heng, predicted that the PAP team would win 80 to 85% of the votes, putting the WP at risk of losing their Ang Mo Kio deposit. However, Yaw's team managed to secure more than one-third of the votes.

Expulsion from party In January 2012, news of a rumoured extramarital affair with a fellow member of the Workers' Party broke out. Yaw said he did not intend to respond to the rumours. A married Chinese woman also claimed to have had an affair with Yaw. After Yaw's resignation of his treasurer post, netizens queried and speculated on the reason for his resignation. On 15 February 2012, the WP announced that Yaw had been expelled with immediate effect, citing "several indiscretions in his private life" as grounds for expulsion. The CEC invited Yaw to explain himself several times, but he failed to attend the meetings. He was admonished for "[breaking] the faith, trust and expectations of the Party and People". On 22 February 2012, Yaw emailed the then-Speaker of Parliament,
Michael Palmer, to say that he would not be contesting his expulsion. As a result, his seat was deemed vacant from the date of his expulsion on 14 February 2012. Yaw resided in Myanmar from late 2016 after he was expelled by the Workers' Party.
Career outside of politics Yaw founded and managed an enrichment programme development firm, Eduhearts Consultancy from 2005 to 2012. After the end of his political career, Yaw, under the alias Amos Rao, went to Myanmar to work as a senior vice-president at Shenton Co, a private education training institute, and the general manager of three subsidiaries there, including Temasek International College, which awarded degrees and diplomas in international business and hospitality. ==Personal life==
