As top sportswear brands prepare to showcase their newest products at this year's World Cup in Germany, many workers who make the products are said to be facing intimidation or dismissal for attempting to unionise, according to a report released by Oxfam International.

Oxfam's report, Offside! Labor Rights and Sportswear Production in Asia, found that workers making clothes, shoes and other goods for global sports brands have been fired or threatened with violence when they have organised unions to lobby for better pay and conditions. Oxfam said that the big sports brands are not doing enough to solve the problem.

Oxfam has carried out a year-long survey of 12 sportswear labels and found labour abuses at facilities producing goods for some of the world’s the best known brands.
