@biscuitlover09876 the king stuff doesn't really impact on us, we just know not to talk politics at all as we don't want to offend people. As a foreigner, that's true in lots of countries! There are certainly lots of foreigners here who slate the country, the people, the bar girls, the government etc, but to me it feels like hypocrisy and entitlement. You shouldn't choose to live in a foreign country and then moan constantly, expect everything to be like 'back home' etc. I often think those people are bitter and cynical and should go elsewhere! Why live here if you hate it so much?! I think maybe they just like complaining 
The international schools vary greatly as there are LOADS of them here, with new ones still opening. Some are British 'brands' like Harrow, Brighton, Rugby, and newly opened King's College and Wellington. A few are part of international school groups, like chains. And then lots of other more independent ones, most for profit but a few non-profit. Generally speaking in the international teaching world, non-profits are the best to work at (but that is a generalisation!) We have lots of British, IB, and American curriculum schools but also Australian, Singaporean, French, Swiss, Japanese etc.
Some schools are not great but most are very good, though not always in comparison to a private school in the UK. Most have very good facilities and some are amazing! There is a new school near me called Verso, which is a high-tech, modern place that claims to have thrown out traditional teaching methods and calls teachers something else like 'learning designers' or something like that! I believe teachers there earn ridiculous salaries, like £5k a month (presumably plus housing allowance, flights etc). I thought about applying but don't think I would have a clue what to do with myself there!!
The kids are generally great. Most schools claim to have more foreigners than they really do, and often count mixed kids as foreign to massage their numbers, even if they are culturally and linguistically Thai. Big nationalities in Bangkok include Japanese, Korean, Chinese as well as a mix of European, Australian etc. A few from various African countries and India. There are lots of Thai Indians though so Indian students are often locals, if that makes sense. At my school I find the kids quite apathetic and certainly the rich Thai kids can be very spoilt, whereas the foreigners are more likely to be UN, diplomatic, or corporate kids who are obviously comfortable but not necessarily loaded. We have Thai teenagers whose parents just buy a house or apartment near to school and they live there on their own while their parents live and work the other side of the city of elsewhere. They have a nanny/helper but basically live alone. I always find that a bit weird!
Also the Thai kids can get into university with very little in the way of school qualifications, so unless they intend to study abroad they don't have to really succeed at school. Some leave after Year 11 or 12 and go directly to Thai university. Even if they want to study abroad, they can do that by getting an undergrad here and then going later. So there is not enough emphasis in some families on the kids doing well.
I'd say behaviour is similar to a private school in the UK. Of course there are issues sometimes but nothing I haven't seen before, and generally the kids live in a bit of a bubble. Some are out partying etc and have no parental supervision, but many are not very worldly at all!
I find the work life balance better here than in the UK. Certainly less paperwork involved! But staff turnover is generally quite high as international teachers often move along, not because they aren't happy or they're not doing a good job, but just because that's their nature. Kids also come and go due to relocations, which means generally students are very used to this and integrating is not hard for new kids. So that's nice. My own children are very happy but they're still young.
