I can’t speak for the countries you mention, but I can give you an insight for The Netherlands.
First of, there is a big demand for English teachers in highschool (students aged around 12 to 18).
But. To become a teacher you need a university degree. Either a bachalors degree or a masters degree (masters unlocking the later ages/classes). See the following page for details: https://www.rijksoverheid.nl/onderwerpen/werken-in-het-onderwijs/vraag-en-antwoord/welke-onderwijsbevoegdheden-zijn-er
Also note that being a teacher is a tough job. Budget cuts have put a lot of strain on the sector, and the teachers do feel that. A lot of people burn out. However, the pay is decent, so if you love the job, you can thrive.
I mention all this, because I suspect that it is similar in other European countries. Hence, to get a good job will require proper preparation and some dedication. Maybe studying abroad in the country you want to move to first.



The SMS messages that my provider sends me when they see I have crossed a border explicitly state there are no extra costs. Minutes/bytes are taken at the same rate from the same bundle.
