Exeter University students and lecturers could work up to 9pm if new timetabling proposals go ahead.
The City University have asked students and staff for feedback on the proposed to extend the teaching day.
These include teaching until 9pm on Thursdays, as a solution to limited teaching spaces on campus.
Other options include extending the teaching day from 9am to 7pm on Monday, Tuesday and Thursday, or beginning teaching at 8.30am each day of the week and finishing at 6.30pm on Monday, Tuesday and Thursday.
A university spokesperson said: “No-one will be expected to teach more hours or attend more lectures than they currently do.
“A university-wide consultation is now under way to enable the project team to gain feedback from the university community as to the impacts of each option on those likely to be most affected.

“The teaching day working group, with the student voice comprehensively represented by the Guild, has conducted a thorough sector-wide review and distilled all the evidence into three options for change.”
The University of Exeter’s Students’ Guild has started a consultation on the proposals, asking students to provide feedback regarding the potential changes.
The guild itself has also states it does not support any of the suggestions. Hannah Barton, guild president, said: “I have serious concerns that changes to the teaching day will negatively impact on the student experience.
“There is strong potential for the proposed changes to affect quality of learning in the classroom, the accessibility of lectures for some and the availability of extra-curricular activities – with many other consequences along the way.
“The students’ guild will continue to press for concessions to these proposals to mitigate any negative impact.”
The consultation will run throughout this month, with an option for change being put forward on July. A pilot scheme would be introduced for the 2015-16 academic year.
In its consultation document the university says the timetable changes are needed because “consistent growth in both staff and student numbers coupled with an increase in modularity and choice has resulted in an unsustainable level of demand on teaching spaces.”
It adds: “Protection of Wednesday afternoons from compulsory undergraduate teaching, in order to support guild, sport and other activities, is maintained in all three options as part of a commitment to the distinctive Exeter student experience.”
