Jason Moyer-Lee described the case as another 'domino' within the changing law around the gig-economy, signifying progress in the IWGBs aim to ramp up the pressure against these employers. In September 2017, the IWGB launched a new campaign with its University of London branch, demanding that the university end outsourcing, implement promised pay rises, and abolish all zero hours contracts at the institution. The campaign was supported by John McDonnell MP, Shadow Chancellor, as well as the co-leader of the Green Party, Jonathan Bartley, who wrote a letter to Adrian Smith, the Vice Chancellor of the University of London to express his concern at the employment situation at the university. The campaign began in earnest on 27 September where porters, security officers, receptionists and post room workers all went on strike. The IWGB organised a 'Precarious Labour Strikes Back' protest that day at Senate House, joining the picket line, as well as in support of another IWGB campaign concerning Uber, which took place at the TfL offices in central London. Alongside strike action, the IWGB also launched a legal challenge to the University of London over the rights of 75 of their outsourced staff to negotiate their pay and conditions directly with the university itself. The IWGB, with the legal aid of the Good Law Project cited Article 11 of the European Convention on Human Rights to argue that the University's failure to negotiate directly with their de facto employees constituted an infringement on the right to collective bargaining enshrined in the convention. The case was considered a landmark legal challenge, with the potential to revolutionise the rights of outsourced workers in the UK. Whilst the initial actions by the IWGB did force a review of facilities management contracts at the university, the University of London still failed to meet the IWGBs demands. As a result, the IWGB organised a second strike, which took place between 25 and 26 April 2018. Outsourced workers at the University of London walked out in protest at the university's continued failure to improve working conditions for outsourced staff, and to demand that they be brought back in house, with the same employment rights as other university staff. With more than 100 workers walking out, the strike became the largest strike by outsourced workers in higher education yet. Following the April strikes, the University of London released a statement in June 2018 declaring that they would begin to bring some of their outsourced staff back in house. Although the statements were vague on timings, some concessions were made to the IWGBs demands, including an acknowledgement that direct action had influenced the decision.
