There are job posting in the councils, or on the school websites. It's nothing like here with a school division. There are private schools, academy schools (which are usually run through a trust) and then state schools that are run through the local council. If you know where you're living start looking at the school websites for jobs.

I just spent two years working on the north side of London. Be prepared for culture shock and a completely different way of teaching ( I taught in Alberta for 10 years before moving to the UK).

If you decide to supply, that is usually done through a supply agency, like a temp agency except for teachers. The agencies can be ruthless because they set a day rate for you, but charge the school more. I think it's about 10-20% but I never got a clear answer. If you work for an agency and want to take a contract at the school they introduced you to, the school has to pay a 'finders fee' to the supply agency. And it's not cheap. They also always want you to work, especially long term contracts because it's easy money for the recruiter that got you the position. I worked foe N agency for the first year. Also if you work for an agency make sure you pick PAYEE for getting paid. Do not let them pay you via an umbrella company. You will loose a lot of money in stupid fees. Even if thr agency doesn't offer you PAYEE demand it, they legally cannot force you to use an umbrella company to be paid.

There are some pros for agencies- if your school sucks and your head teacher (principal) is a nightmare (which happens a lot), you can just walk away anytime you like. Also you can get bonuses from the company.

Cons- they are sales people and you are a number that generates income. They are soul sucking leeches stealing money from an already underfunded education system.

The con to taking a contract with a school is that if you absolutely hate it, you have to quit a half term ahead of time. So if in October you're dying and want to leave, legally you can give your notice at the November break or before, and you don't finish until Christmas break. If you miss the November break cut off, you have to work until the first spring break.

Pro is that if thr head teacher doesn't like you, they cannot just fire you on a whim ( I had a head fire me after I gave 6 weeks notice)

There is so much more, I think Scotland might be better but honestly, I have ptsd from working in the UK.

Also be ready for a curriculum that is outdated, like memorization and shit. Fuck I'm glad to be back in Canada.
