Both Douglas high schools are now asking some students to stay at home tomorrow.
St Ninian’s has joined Ballakermeen in asking students not to come into school due to a large number of staff absences.
A letter from Headteacher Chris Coole to parents said the school had ‘exhausted all other contingencies to manage this for the remainder of the week’.
Mr Coole added: ‘The current situation is therefore not sustainable so I have had to make the very difficult decision to inform you that all Year 9 students should remain at home tomorrow (Friday 7th January) and not come in to school. Whilst at home students should continue to access their usual lessons via their Google Classrooms which should have key resources and assignments available for them to learn from during the day.
‘Please be assured that this decision has not been taken lightly and we have tried to do everything to avoid this scenario but with the volume of teaching and support staff currently absent and a reduced availability of supply teachers available I have little option. A decision as to what contingencies may need to be in place for next week will be made tomorrow and all parents will be informed of these as soon as is possible.’
