Your job plan should account for your non-clinical work. If not, speak with the DMT. The good part of an annualised rota is the flexibility it gives you in when non-clinical work can be done. The danger is that people voluntarily overwork in the gaps which also make up their leave. This is why some people will choose to "book" leave to better define when it occurs. However, even if you do not book any leave at all, it is still given to you automatically as the DCC calculations already includes leave. It will not be in specific, identifiable, defined periods however.
