In 1967, the London School of Economics suspended two students for taking part in demonstrations. The harsh treatment of the duo inspired their peers to hold a sit-in protest and a boycott of lectures. Within weeks, the suspensions were lifted. This began a decade-long student movement that took on social injustice at every turn. Protesting racism, US foreign policy and a whole host of other issues went hand-in-hand with studying in the UK.

Fast-forward 46 years. The University of Sussex suspends five students for their involvement in an occupy-style campaign. University management refuse to release evidence of the disruption they have caused and the student body is moved to action. More protests are arranged, a petition is started, messages of support flood in from MPs and academics. Within less than two weeks, senior management buckles to the pressure and the students are reinstated – with a renewed confidence that they can stand up to authority and force through change.

Student protest is back.

The Occupy Sussex movement, which first saw students protesting in February , started as a campaign opposing plans to outsource campus services to private contractors. Activists complained that the process had not been transparent, students and staff had not been consulted and the university had refused to consider the alternatives to privatisation. They occupied a conference centre on campus and protests continued for several months. The movement peaked with a 1,000-strong student march held on campus.

The occupiers inspired their peers at other universities to start movements of their own. Birmingham, Edinburgh, Sheffield, University College London and Warwick are just some of the institutions that have hosted similar movements over the past year.

At each university, students have had separate grievances. Some have opposed campus sell-offs, others have objected to the increasing pay of senior management and many have fought against the privatisation of student debt. What underlies and unifies all of these protests is a frustration with what activists call the "marketisation of higher education". In other words, they oppose universities being run like businesses, rather than the unique public institutions that they are.

Until recently, these campaigns have largely slipped under the mass media radar. One reason for this is that they have been transient and only locally coordinated. Although students are keen to show solidarity with those at other universities, the protests have not followed a national timetable. It must also be noted that the movements have not yet attracted the same widespread support of the 1960s campaigns – in the wake of the LSE suspensions, 100,000 took part in a single protest.

However, all this might be about to change. When the Sussex Vice Chancellor suspended a handful of protesters, he galvanised a large number of otherwise apathetic students. Instead of quelling the protests, this exercise of power gave activists a new, perhaps more tangible injustice to fight. Students at Sussex talk of the suspensions polarising opinion and engaging those who had previously been cynical. At the end of last month, Facebook logged just under 2,000 people talking about the 'Occupy Sussex' page. That number now stands at just over 5,000.

A similar thing is happening in London. Earlier this month, campaigners demanded that their outsourced campus cleaners be granted the same sick pay, holidays and pensions afforded to university staff. Protesters were forcefully dispersed and subsequently, The University of London, which represents a number of institutions, including – somewhat ironically - the London School of Economics, banned on-campus protests. This has only strengthened the resolve of campaigners (who were marching to oppose increased police presence on campus only days later) and media interest continues to grow.

By refusing to genuinely engage with students, managers have painted themselves as the pantomime villains of this year’s protests. Their heavy-handedness has become a powerful recruitment tool for existing student activists. Managers have encouraged more students to challenge the dictatorial authority they have embraced, as well as their acceptance of the 'marketisation' agenda.

Perhaps it is premature to declare the birth of a new mass movement. With Christmas approaching, the protests may well quieten down. But they are not going away. Students will return in the new year, with another three grand of debt and an ever growing sense of frustration. And you'll hear about it too.
