Labour leader In 1982, Oshiomhole was appointed general secretary of the
National Union of Textile, Garment and Tailoring Workers of Nigeria, a union with over 75,000 workers. After
democracy was restored in 1999, he became president of the
Nigerian Labour Congress and was prominent as the leader of a campaign of industrial action against high oil prices in Nigeria. Early in the administration of
President Olusegun Obasanjo, he negotiated a 25% wage increase for public sector workers. In return he publicly supported Obasanjo and endorsed his candidacy when he was re-elected in 2003. The textile workers union elected Oshiomhole for a second term as general secretary while he continued as president of the NLC (Nigeria Labour Congress). His relationship with Obasanjo turned sour as neglect of local oil
refineries led to the reliance on imported
gasoline, followed by rises in the price of fuel. Oshiomhole led strikes and demonstrations against the increase. He faced arrests, tear gas and temporary blockades of union offices, and Obasanjo introduced legislation to make it more difficult for the NLC to strike. He represented African workers for two terms on the governing body of the
International Labour Organization (ILO), serving on the committee on freedom of association. He was also a member of the executive board of the
International Confederation of Free Trade Unions. The decision was based on several voting irregularities. During the
2012 Edo State gubernatorial election, he was elected to a second term, winning the elections in a massive
landslide. His tenure ended on 12 November 2016. On 23 June 2018, Oshiomhole emerged as the national chairman of the All Progressives Congress (APC) following a voice vote by delegates at the party's national convention. On 12 November 2019, Oshiomhole was suspended from the APC after 18 local government chairmen of the party in his native state of Edo passed a
vote of no confidence on him. He was accused of trying to disintegrate the party in Edo State. But a faction of the party loyal to Oshiomhole declared his suspension null and void and then suspended Governor
Godwin Obaseki of the state whom they say orchestrated Oshiomhole's suspension. On 15 January 2020, Edo APC reaffirmed the suspension of Oshiomhole and said he had no legal right to continue to function as the APC national chairman by the virtue of his suspension in Edo State. On 4 March 2020, a high court sitting in Abuja ordered the suspension of Oshiomhole from the office of the national chairman of the APC, that having been suspended from the party, Oshiomhole was no longer a member of the party and could not possibly continue to discharge his official responsibilities as national chairman with a clear order of the court that Oshiomhole be restricted from the national secretariat of the party. Armed security agents, including the Police,
Department of State Service (DSS) and
Civil Defence were heavily deployed to the secretariat to prevent Oshiomhole from entering. On 5 March 2020, a federal high court in
Kano gave another judgement which vacated the judgement of the Federal Capital Territory (FCT) High Court and restored Oshiomhole as the national chairman of the APC. This created confusion as to which judgement to obey because both courts (FCT High Court and Federal High Court Kano) are of equal jurisdiction and none of them could vacate the judgement of the other. Oshiomole appealed against his suspension at the Abuja Court of Appeal and the court affirmed his suspension on 16 June 2020. On 28 May 2022, Oshiomhole won the APC primaries for the 2023 Edo North senatorial elections. On 26 February 2023, INEC declared Oshiomhole the winner of 2023 senatorial election for Edo North senatorial district. With 107,110 votes, Oshiomhole was declared the winner of the polls, defeating the incumbent Senator Francis Alimekhena of the Peoples Democratic Party (PDP), who scored 55,344 votes. He was named Chairman, Senate Committee on Interior of the 10th Senate, on 8 August 2023. == Controversy ==
