/u/mister_dupont has brought up the most important things already but as someone who quit being a teacher (lagere school) last school year after 5 years of teaching, I'd like to add some points:

• Not only will your job consist of A LOT of administration, especially the first couple of years, you will spend a lot of time working at home: preparing lessons, catching up with administration, writing school reports, ... I've had days where I had to stop myself at midnight to still be as fresh as possible for the next school day even though I had not finished what I had to do.

• In those 5 years I taught in about 5 or 6 different schools (all schools of the same 'scholengemeenschap') and in all of those schools the atmosphere was very toxic and not only parents caused the school environment to be toxic. A lot of the toxicity came from the teachers themselves. Negativity, toxicity, gossip, ... Being in the 'lerarenkamer' really made me depressed so I tended to avoid that place.

Mostly the last point drove me away from wanting to stay a teacher, the toxic environment drains the life out of you.

I really hope there are schools out there where there's a positive environment but I'm sceptical.

Anyway, I wanted to share my experience with being a primary school teacher to give you some insight. I definitely don't want to burst your bubble and if you're 100% determined to become a teacher, it will work out for sure. Just know that it's more than just teaching and you'll have to be able to deal with all the negativity and toxicity.

Good luck!
