You should remember that working for free or 'just a couple of beers' is taking work away from people who do it for a living and that agreeing to work for such a low rate allows employers to keep lesson fees low.
Fair enough, I see your point, so what should I charge? Suggested hourly rate, please, for a big city student receiving 1-1 tuition from someone with an English language qualification but not a TEFL qualification? Is the 50zl per hour I have been offered too high or too low?
Also, any idea what the social insurance fee is, and does it fluctuate if my pay goes up or down? Looks like I will be making £80 a month, approx. 19% of that will go in tax plus social insurance of ...? Any idea?
You'd be teaching English, not Polish.
Well, I am amazed at that being possible in Poland, in the UK teachers of, for example, French or German, would be lost if they couldn't communicate grammar and syntax ideas in the student's native language of English.
In 2012 you can earn 3091zl / 5 = £619 (without paying any tax)
Just £600 before you have to pay tax in Poland? ! My oh my!
Isn't the UK increasing it to about £10K from £7K this next tax year? Maybe I misheard on that.
