On 23 October 2013 Ineos announced the closure of its petrochemical plant in Grangemouth, Scotland, following a dispute with the Unite trade union over pensions and an attempt to impose a wage freeze and new contract on the workforce. However, by 25 October 2013 the union capitulated to the closure threats and agreed to all Ineos's demands meaning the plant would stay open and strike-free for three years. In September 2016 the company completed a new headquarters building at Grangemouth as part of a "site rejuvenation plan".
