The Supreme Court’s ruling was the second unfavourable decision for Walmart in a week – on 9 December, a judge found that the retailer had threatened employees who were attempting to organise action to challenge Walmart to increase wages and benefits.

Walmart was recently ordered to pay a massive US$188m to employees after the Pennsylvania Supreme Court ruled that the company failed to compensate workers for rest breaks and all hours worked.
