Justin Br, is your salary openly available to anyone who wants to see it? Are all your benefits easily viewed on your company website? I'm not sure why you think a teacher's full salary/benefits package should be.
I work at an
International School. The teaching circuit here is very small, so international school teachers will often meet at conferences, meetings and collaboration groups.
Lower paying schools will offer a teaching couple $2500 a month, but higher end payers provide couples/families with up to $3800 a month. Single teachers get less, but the lowest I have heard of is $1700 a month.
Salary scales will start (and this is for an inexperienced teacher) at around $45-65,000 - depending on the school. They go up, and vary significantly, from there. Many schools pay a gratuity or completion bonus of around 10-20% of salary. No, I don't have "evidence" of what I'm saying. Sorry, you'll just have to take my word for it.
I was recently at a party with a range of people from a variety of industries. When I divulged my salary (which is actually very good compared with what a teacher would earn at a local school, or would earn at home) I was met with total shock and concern about how on earth I afford to eat, pay rent and raise children... Most expats (and yes, I'm talking about the professional ones) here are not earning under $100k a year. Why is it so outrageous for teachers to be earning a semi-decent pay packet? My non-teaching expat friends earn probably double what I make, and they are about the same age as me...
(And the comment about universities: yes, it is widely known that universities here are terrible payers. This is why you'll find most lecturers are either local, short-term/visiting expat lecturers OR have been here for donkey's years and are earning heaps because those were the benefits in their original contract.)
