The college was accused of “institutional racism” last month after its governing body said it would not seek to move the monument from its position outside the building.
The academics have now announced a boycott of tutorials to Oriel’s undergraduate students and will refuse to take part in any outreach and access work including undergraduate admissions interviewing.
They have also pledged to not participate in recruitment and assessment processes for fellowships at Oriel and other Oriel College appointments, along with boycotting talks, seminars and conferences.
One of the signatories to the petition said that the boycott was of “discretionary” activities rather than any formal organised teaching or lecturing.
