Not a great time of yearfor jobs unless you're in a city with lots of business English 1-2-1s on offer i.e. Warsaw.
Looked at one or two pages of your site, probably all useful stuff but (sigh) no apostrophe in PCs, nor in 1990s... etc. Please read theoatmeal.com/comics/apostrophe
Pretty essential that teachers know where an apostrophe goes, or they shouldn't be teaching.
Anyone looking to teach should try to get the concessionary rate at a college in the UK so that their CELTA either costs nothing at all, or is seriously discounted. Blowing a grand on a course in Poland should only be done if a proper job offer is lined up.
With an advertisement like that, it's not surprising that he has stooped to 20zł an hour.
It is struggling - please refer to my previous posts where I have spoken to teachers who tell me that. Belt squeeze time right now - the cheap supermarkets are seeing a surge of customers. This ripples across to all sectors, or nearly all.
As for the 20zl person - not unique. Plenty at 30zl advertised on those stickers. Very few strips torn off.
What's more - I have made it my business (sad I know) to talk to lots of supermarket staff these past few weeks. Almost all speak pretty good English now, I gather mostly via school classes. Fewer and fewer people need additional coaching.
