You can either teach, or you can't - it's that simple really (but read up on the language and meths with tomes by Jeremy Harmer/Jim Scrivener and Michael Swan........)
I have a chap working with me. He doesn't have a degree. doesn't have the CELTA - but boy can he teach! I don't know whether it's his charisma or his patient but jolly demeanour, but companies love him. He turns down work - or more often than not doesn't bother responding to an enquiry. It's in a mining city in the south of Poland that rhymes with cat......
A one-off I suppose, as they always ask to see my certificates :(
Regarding the Umowa o Dzieło..."
Yes InWroc - I was working for a head office. When I started, they were at one level. When the contract finished they were at a higher level in terms of colloquial usage. (B2 learners). Job finished.
Sick of waiting for the Polish scum government to reform this unfair tax.
Anyway the umowa o dzielo said " Usługa Konsultacja" - so it's hard to prove anything either way shirley? I will leave my happy home in ole Polska if necessary rather than permit ZUS to ever steal from me again.
Poll tax all over again, innit?
