Continual Medical Education (CMEs) are definitely during normal work days. They're also often at fancy destinations with hotels and mai tais. My father and other family have done them for years. They never had to take vacation days.

Doctors have a terrible working schedule and I'm not jealous of it one bit, but this is really not true.

They may be on-call sometimes but generally if they're off they are not working or training.

They read UpToDate on work time.
