Caroline Lucas, Green Party joint leader and Brighton Pavilion MP, has joined the Independent Workers Union of Great Britain’s (IWGB) Senate House boycott.

In a statement she said: ‘I strongly support the action being taken by the UoL workers – it is completely wrong that they are subject to worse terms and conditions than directly employed workers. Like you, I am deeply concerned about fundamental changes in our labour market in recent decades, including the spread of outsourcing by public bodies: well-paid jobs on permanent contracts have dwindled, while bogus self-employment, zero-hours contracts, and low pay are rife.

‘With wage growth stalled, the high employment rate masks the insecurity faced by huge numbers of workers. So I am very happy to join my Green Party colleagues Sian Berry and Jonathan Bartley in supporting the boycott.’
