Official analysis indicates that Labour's proposed crackdown on zero-hours contracts could cost businesses between £350 million and £2.9 billion per year. The reforms, part of the Employment Rights Act championed by Angela Rayner when she served as Deputy Prime Minister, aim to provide workers with guaranteed shifts and compensation for canceled work. While the government assessment suggests a "small, positive impact on growth" by boosting worker wellbeing, it also acknowledges increased administrative costs and reduced employer flexibility.

The analysis projects the most significant impact in sectors with variable demand, such as hospitality, retail, and healthcare, where flexible staffing models are common. The reforms could make it more difficult for employers to adapt to fluctuating demand, potentially affecting output. The overall net cost to the economy is estimated to range from £300 million to £1.4 billion annually.

Industry leaders have expressed concerns that the reforms could exacerbate unemployment, particularly among young people. Tina McKenzie, head of the Federation of Small Businesses, criticized the timing of the cost announcement, noting a recent increase in unemployment since Labour took office. She warned against a repeat of past economic difficulties for small businesses.

Neil Carberry, chief executive of the Recruitment and Employment Confederation, stated that the government's cost estimate may underestimate compliance and processing expenses for businesses. He warned that an additional £2.9 billion in employment costs could worsen youth unemployment.

Kate Nicholls, head of UK Hospitality, argued that the sector, which employs many young, part-time, and non-graduate workers, should be incentivized rather than burdened with additional costs. She noted that the cost benefits for employees appear to be outweighed by the expenses imposed on employers.

A government spokesperson affirmed a commitment to ending exploitative zero-hours contracts and ensuring greater income security for workers. The spokesperson added that consultations are ongoing to refine the details of the reforms and ensure their practical implementation. The exact cost to businesses will depend on the threshold set for workers to gain the right to guaranteed hours; a threshold of eight to 20 hours per week, favored by the government, would result in lower direct costs.
