Prior to the 2016 referendum on the UK's membership of the EU, the company's Chief Executive, Janet McCollum, said that the UK should remain within the European Union. The company has used the freedom of movement within the EU to employ over 1,000 workers from countries such as Lithuania, Poland and Portugal at its Northern Ireland facilities. After the UK voted to leave the EU, the company announced that it planned to move its headquarters to the Republic of Ireland.
