I have an office type job.
I do realise it will be harder for those with shift jobs and those where annual leave is restricted in certain periods/ ways.
Are you a single parent? If not, what job does your partner do?
The couples I know who make this work are ones where both partners are fully on board with using their annual leave to cover holidays, and take very little of it together so as to maximise.
I very rarely take annual leave days for myself.
