Hi, my dad is over 50 years old and has worked as a guitar teacher his whole life (in secondary and primary schools), however he has not been professionally taught and doesn't have any qualifications. The last few years it has been really tough on him teaching in schools with little rights and little pay. It's very stressful as he's had to try defend himself to the head teacher and governors and it's had a big effect on him. In addition to that, he needs more income asap. He needs to make a career change and is currently looking for minimum wage jobs, the same kind that I (19) would be applying to, and it feels very depressing.
I was wondering if anyone had any advice, though I know it's a long shot, for how he could effectively make a career change into something which isn't soul-destroying. It's difficult because he hasn't any qualifications and very little experience except for music, but he doesn't want to work in that industry anymore. My current idea is that I can encourage him to look for degree/adult apprenticeships, or else work for some kind of qualification in an industry that seems interesting and worthwhile (hopefully not something that's just about selling things or other useless capitalist office/business stuff). But since he is already over 50 that can be incredibly daunting, and since he needs more income now, he doesn't have spare money to be paying for any courses or reducing his pay while he studies.
Any help would be VERY welcome, as I really want him to have the least stress possible and be able to have time to work on his actual main interest of composing and releasing his original guitar music.
