Political activism
Sandra spoke at the Radical Independence Conference in 2012 on the role of art and culture in changing society. In November 2013, Webster addressed the STUC's disabled workers' conference in Dundee and called for the rights of disabled people to be enshrined in a written constitution in an independent Scotland. She had previously called for carers' voices to be heard during the independence referendum campaign and for carers to be "recognised for the £10 billion we contribute to the Scottish economy". Sandra Webster was re-elected as SSP co-spokesperson alongside Colin Fox at the 2014 SSP conference. She stood at a general electionfor the first time at the 2015 UK general election, as the official SSP candidate in Paisley and Renfrewshire South. During the election campaign, she campaigned to ban zero-hour contracts, saying they "exploit workers and attack their employment rights". Explaining her decision to stand, she said the SSP "offer an alternative to the austerity that other political parties promise to deliver" and the party is "proud to represent all of the working class not just those who are in work". She said she is "possibly the only candidate" in the constituency who has been directly impacted by cuts to public services and is "standing for something real rather than it being an academic exercise". On International Women’s Day on an article published by the Scottish Socialist Party, she claims to have stood by and been most passionate about protecting vulnerable disadvantaged women, such as those with disabilities, carers and women on benefits. She was the no. 2 candidate in the Westregional list for RISE - Scotland's Left Alliance at the 2016 Scottish Parliament election. In 2016, she stood down as joint national spokesperson.
