Mondelez Malaysia. As of 2015, the Aintree factory produced over 55,000 tonnes of products each year, and as of 2022 4,000 tonnes of crackers are produced annually at the factory. In 2015, it received a £10 million investment from United Biscuits to further boost output. Industrial relations The activist and trade union organiser Rosie Hackett worked for some years as a messenger for Jacob's. At that time the working conditions in the factory were poor. On 22 August 1911 Hackett helped organise the withdrawal of women's labour in Jacob's factory to support their male colleagues who were already on strike. With the women's help, the men secured better working conditions and a pay rise. Two weeks later, at the age of eighteen, Hackett co-founded the Irish Women Worker's Union (IWWU) with Delia Larkin. During the 1913 Lockout Hackett helped mobilise the Jacob's workers to come out in solidarity with other workers, they in turn were locked out by their own employers. In 1914 her Jacob's employers sacked her over her role in the Lockout. In 2009, after 156 years of making biscuits in Ireland, Jacob Fruitfield shut its Tallaght plant. 220 jobs were lost while the company retained around 100 staff in a variety of roles. In November 2022, workers at the Aintree factory went on strike after pay negotiations with management since September of that year failed to reach an agreement, and the company temporarily shifted production to Portugal. Staff at the factory are supported in the ongoing strike by the GMB union.
