I was a f/t secondary teacher in a PT (HoD) role.
I now teach adults basic skills (in the charity sector, focussing on young mums with no qualifications, and including "family literacy" - reading with/to young children). This includes coordinating the project, managing volunteers and fundraising.
I tutor Geography privately.
I mark "Higher" Geography each May/June (Scotland).
I do a few hours a week in a voluntary role fundraising/administering for my church's anti-poverty project.
I have 3 dc of 10, 12 and 14, and a dh who works long hours including regular nights/weekends away (he's a doctor).
I'm also disabled with long term neurological issues which affect my mobility, so all these "wee" things suit well and I can gear up to the 3 hellish weeks of marking, putting support in place ahead of time, managing my hospital visits around that time.
I certainly don't earn as much as when I was teaching ft but I wouldn't have been physically able to do it anyway, and I'm really enjoying the flexibility of being in when the dc get home these days.
I realise I'm lucky not to have to work full time, and this suits me and the family very well.
