University staff say they are "disappointed" to be out on strike again as part of a long-running dispute over pay, pensions and working conditions.
Drivers honked their support as around 25 staff from the University of Suffolk picketed outside the Waterfront campus as part of a wave of strikes called by the University and College Union (UCU).
Stuart Lipscombe, UCU branch chairman at the University of Suffolk, said: "It's disappointing for us to be here. And it's disappointing for the students who are missing out.
"But those students need to get hold of Vice Chancellors up and down the country, and write to them and ask them to get around the table with UCU and come to a successful resolution over these issues.
"Our employers have refused to engage in any meaningful negotiations with the University Colleges Employers Association and Universities UK on issues such as pay, working conditions, casualization, equality pay gaps and pensions.
"Our pay has gone down in relation to inflation by 28% since 2009."
Dr Lipscombe said the UCU in Ipswich was a "developing union" and the strike had support among university staff beyond those who were picketing.
Laura Polley, a criminology lecturer, said: "I was on a temporary contract since I started three years ago. I've only just got a permanent contract in the past few months.
"That meant I couldn't even rent by myself. I had to move back home with my parents when I took this job because it's not a permanent income. I couldn't even get on a tenancy agreement.
"There are so many people in my position across academia – here and at other universities – who are on temporary contracts. They don't know where their next paycheck is coming from, and that's not a healthy environment to teach students in."
Ms Pollley said she believes "in the long run" the action is good for students. Adding: "Our working conditions are their learning conditions.
"If we're overworked, stressed out, unsure where our next paycheck is coming from we can't create a healthy and progressive learning environment for them."
Staff at the university will walk out again on Friday, November 25 and Wednesday, November 30. They will also take part in 'action short of a strike'.
The University of Suffolk previously pledged that its facilities and campus will remain open during the strikes and called on UCU members to "consider the impact industrial action has on our students".
