Apple released its annual Supplier Responsibility Progress Report on Wednesday, detailing the ways in which the company is trying to improve the state of its supply chain.

It’s an important practice given Apple has come under fire in the not-so-distant past for its factory workers’ hellish working conditions.

Apple’s latest report includes a number of labour violations the company found through audits last year, most of which can be attributed to “improper provision of wages and benefits and working hours violations,” the report states.

One violation detailed in the report, for instance, reveals that more than 700 foreign contract workers from the Philippines were forced to pay a total of $1 million (£722,000) to work for a supplier, Reuters reported.

Apple paid $1.9 million (£1.4 million) in recruitment fees last year for employees impacted by bonded labour—also known as debt bondage, this is when a person is hired under the condition that their labour is repayment for some type of debt.

In 2008, Apple announced that this violated its code of conduct.
