If you want real job security in teaching, and instant tenure, work for the grade school public education system in the USA. It is like another sub-culture with it's own rules and with the union they can't fire you or make you abide by any policy. Hell the real criminal justice departments can't even touch you unless you commit a crime off school property on your own time.
Also, decent pay way few hours than a real job (something like 4 to 6 hours a day and 8 months a year) which allows you to do hobbies, take long vacations, and get a part time job for side money all at the same time. And, it gives a ton of vaction and sick pay and days off. And, you are ression proof and will get pay raises every year no matter the condition of the State budget. Plus, no accountability and you can do whatever you want and treat the kids anyway you want once you get automatic tenure after 90 days or a year (depending on your school district). And small class sizes of 11 to 14 (way less than college classes). And you get Aids or Assists to joke around with if one of the kids has a special education plan. However, the only problem with public school employment in the USA is it lacks challange, and you may get bored and want to realy contribute to society, or even go abroad and see different cultures and worlds. But the best part is you will be working with other adults who who are all about getting even more time off and making more money.
Just avoid working public schools in other countries it is a total challange because you will have standards to meet, and you will be held accountable, and the pay sucks, and you will have way longer hours and will be forced to do real work.
Good luck, hope you can get a real job.
