Naming [...] companies in Britain that exploit workers and dishing out large fines can help stamp out abuses, pressure groups said on Tuesday, welcoming draft legislation aimed at closing loopholes that allow modern slavery to flourish... Employers in Britain can expect their labour practices to be inspected only once every 500 years on average, and receive insignificant fines if they break labour laws... More frequent and comprehensive workplace inspections and larger fines would help to root out abuses and protect vulnerable low-paid workers... Under Britain's 2015 Modern Slavery Act, companies with a turnover of more than 36 million pounds [...] must produce an annual statement outlining the actions they have taken to combat forced labour within their supply chains... Most of Britain's FTSE 100 companies have taken a "tick box" approach, with half providing "no meaningful information" about steps taken to tackle slavery in their supply chains, said the Business and Human Rights Resource Centre (BHRRC) last month.
