^^^ There aren't that many jobs, Canary42, where staff are often expected to undergo training in their own time and unpaid.
For example, as there was no qualified first-aider in the school that I taught in, I was pressured go on the training course (which was spread over several weeks, with one evening session per week). Not only was I not paid for my time but the education authority billed me for the tuition! (I eventually managed to get that debt written off after the intervention of my union).
Similarly, as the only teacher qualified to assess students on a GCSE-equivalent course was on maternity leave, I was informed that I'd have to cancel my holiday abroad (losing the deposit) and spend the half-term week on a course to get the relevant qualification. Again, I was offered no extra pay.
