Sussex House targeted by the march

The group of protesters marched on Sussex House, a hub for university staff. Home-made banners with slogans such as "Adam Tickell what a FUUKing sell out", "Slay the neo-liberal beast" and "Back 2 bed for the UCU" were carried by protesters.

Whilst they marched they chanted "this is what democracy looks like" and "when I say cut backs you say strike back”

All alcohol removed from on-campus Co-op

The on-campus Co-op has removed all alcohol from its shelves as a safety measure against the national demonstration.

Students occupy new East Slope building

A group of 40 students are occupying a building on the construction site for the new on-campus accommodation, demanding reductions in rent as the cheapest accommodation is being replaced by the most expensive. This means that protesters are using the momentum, and coverage, of the UCU strikes in order to fight for other causes. The occupiers stated that they "will be halting construction for as long as it takes to force management to meet our demands."

Nearly 600 clicked attending on a Facebook event for the demo, with a further 800+ expressing their interest. The last time a demonstration happened with such impact was in 2013, when protesters rallied against privatisation of on-campus services. This time, the demonstration was organised as an act of solidarity for tutors who are caught in a battle for their pensions, their futures.

Chris Chapwin, head of UCU, told The Tab Sussex "its been a good turnout, I think the worry was that loads of students would turn up and start damaging stuff but they've been amazing."
