Folks with an attitude like yours are part of the problems in ESL rather than of their solution. It is quite legitimate under certain circumstances to do a runner if you are not happy in your current job - for example, if the employer fails to pay you on time and in full and after consultations with the employer have turned out to be to no avail. Employing and being employed is primarily also an act of business between the two parties, and if things don't work out you should leave or fire an unsuitable person instead of keeping such a problematic relationship up to the "bitter" end. People should be allowed to keep control over their own lives even when working abroad and changing an unsuitable employment is not easy there due to legal and administrative restrictions. Qualified people will find employment everywhere and basically can only improve their own situation in looking further for better employment. Unqualified folks tend to depend on their crappy employer and are less flexible for obvious reasons. In general, unqualified people should not be allowed to work in education at all.

I note that her critics like to run away from jobs, even to the tune of two jobs in two weeks.
