How often does this happen? In the last few months I've read a few people (on RFA facebook groups) saying they've been put on a course or called back to a ship early while on leave. I've now seen it once too often to overlook it as a one off. So I have a few questions, i) How often does this actually happen? ii) Are you obliged to do it? iii) Are you compensated when it does happen? Any other relevant info would be greatly appreciated.
