Some students asked to stay home on Thursday and Friday
Staff absences at Castle Rushen High School are affecting classes for the rest of the week.
Year 9 pupils are being asked not to attend classes at all tomorrow, whilst on Friday Year 10 pupils are asked to attend their maths mock exam at 9am and then leave school straight after.
Headteacher Mr Keith Winstanley says it's 'not yet clear whether they will be able to teach all other years in school' for the rest of the week.
He says they will try to provide as much notice as possible of any further disruption.
Parents of students at the school are asked to check email and phone messages each morning.
