The issue is similar, but not the same, for freelancers. There is a fear that one cannot ignore calls from agencies, queries from the current client or contact from previous clients. The reality is that it can usually wait.

Ironically, during my holiday this year the only contact I needed to have was because SSC decided to post my first editorial (I am sure I could have contacted to have it rescheduled a few days earlier or later). I felt obliged to try and check the discussion thread and did so throughout the day. At least that was not the same as someone calling you up, with you knowing that they are one smidge of lost patience away from asking you to come in.
