A TOTAL of 35 compulsory redundancies are to be made at the three schools run by the Island Innovation Trust, in a bid to balance the books.
Carisbrooke College, Medina College and the Island Innovation VI Form Campus, are all set to lose staff.
The job losses are in addition to a voluntary redundancy scheme, through which it is believed nearly 30 staff are to leave.
Nine teaching posts are believed to be going in total, including two through compulsory redundancy.
Most compulsory redundancies are among support staff, where 33 jobs will be lost.
A campaign has been mounted by students to retain the staff and by yesterday 100 students had signed it.
Trust chair of governors, Terence Hart said: "Our overriding aim is to create a sound financial platform for continuing improvement in the quality of teaching and learning across both colleges and the VI Form, and build on the good progress that we have made so far."
He added that although the voluntary redundancy scheme had gone some way to helping, further savings need to be achieved.
Public service union Unison branch secretary Mark Chiverton said he understood Carisbrooke College has to save £580,000 and Medina College £304,000, both by 2016. The savings are required to offset falling student numbers.
He said there had been 21 voluntary redundancies at Carisbrooke College, including seven teachers, and a further seven support staff and one part-time post at Medina College.
"It’s bound to have major implications for the workforce and the delivery of the curriculum.
"It is very disproportionate, massively affecting support staff, many of whom are on low pay."
Students from across all three campuses have signed a petition against the cuts.
Addressed to Emma Shambrook, the clerk to the governing body, it said: "We, as the student body, cannot allow the redundancies to take place across the three campuses. We are urging you to please reconsider your decision, by taking into account the impact it will have on the students at the three campuses."
