ATA is already under US investigation over forced labour allegations. Dyson has terminated its contracts and is in talks with its customer over the audit findings. ATA, which produces parts for Dyson's vacuum cleaners and air purifiers, tumbled 30% to its lowest since April 2020. The termination is a significant blow for Malaysia, a major electronics manufacturing hub, which has faced scrutiny this year over claims of abusive working and living conditions. Dyson terminated the relationship with six months' contractual notice, hoping it would give ATA the impetus to improve and enable an orderly withdrawal in the interests of the workers they employ.
