The research also found the gig economy to be linked to a growing number of cases with companies like Uber and Deliveroo repeatedly associated with allegations of abuse using gig workers.
It found 665 cases and 489 named companies linked to cases, which also included Carrefour, Aramco, Giorgio Armani, John Lewis, Marks & Spencer, Toyota, Samsung and the Saudi Public Investment Fund (PIF).
Meta, Uber and Deliveroo are among the firms that have been linked to cases of alleged abuse against migrant workers last year, according to an analysis.
John Lewis said the two cases it was linked to in the analysis were associated with an ongoing investigation at a factory in Jordan, which does not supply its own brand products but two brands widely stocked at a number of retailers.
Isobel Archer, BHRRC’s senior researcher in labour and migrant worker rights, said: “The reported cases we have tracked are almost certainly only the tip of the iceberg.
