In 2015, ABC's Four Corners reported widespread wage theft and exploitation at 7-Eleven franchise stores. In response, the SDA established a hotline and dedicated team of industrial officers to help workers recover lost wages. The union has made numerous submissions calling for a reform of the Franchise Code of Conduct. Following the 2017 launch of Amazon in Australia, the SDA and the Transport Workers Union formed the Online Retail & Delivery Workers Alliance. The alliance is part of a global movement led by UNI Global Union and its affiliates to organise workers in Amazon fulfilment centres. Industrial activity Youth wages Australia operates a system of youth wages where it is legal for workers under the age of 21 to be paid a percentage of the adult wage rate for their job. The SDA has campaigned and called for the abolition of junior wages for decades. In 2013 the SDA began a national campaign to end youth wages for workers aged 18 years of age and the retail industry. This commenced with a case at the Fair Work Commission to remove the ninety percent rate for 20-year-olds in the retail award.

Customer violence and abuse In 2017, the SDA launched a national public awareness campaign to combat what the union described as the growing problem of violence and abuse directed at retail workers by customers. A survey conducted by the union of 6,000 retail and fast food workers found that more than 85 per cent had experienced abuse from customers. Almost three-quarters (74 percent) of respondents were women, and 65 percent of respondents worked in front end services (like cashiers and registers) and just over half (51 percent) of respondents said that no action was taken after they reported an incident. In 2018, the SDA launched its campaign Don't Bag Retail Staff in response to the highly publicised ban of free single-use plastic bags introduced in some states. Public holidays The SDA has advocated for protecting and expanding public holiday rights and entitlements across all Australian states and territories. South Australia & Northern Territory In South Australia, the SDA spearheaded the campaign to achieve part-day public holidays after 6pm on Christmas Eve and New Year's Eve. In 2012, the South Australian government legislated these
