I'll technically be 'fit' I'm sure, but I've basically been told that it would be in the 'too hard' basket to adjust duties etc.

Worked it all out with HR this arvo and feeling a lot better. Basically I'll be 'working' up until 33 weeks, up to the first day of term 4, and my paid recess leave during the school holidays will count as work, and I can use up my accumulated annual leave in the weeks before holidays. Approval from HR to finish in the last week of August.
