Professionally, there will be considerable work waiting for you upon your return. If you have a continuity clinical practice, your patients may have waited to see you which creates an increased demand for your clinical attention right when you get back. Alternatively, they may have seen a covering doctor in your absence, in which case you will need extra time to get caught up on what happened with their care while you were away. Even if you looked at your email while you were on leave, there are likely to be many administrative or academic tasks that now need to be actively addressed.
