The big question is, whom would they lack behind? Journalists? Teachers? Nurses? Pharmacists? Most accountant clerks?
Generally speaking in Poland, you need a Masters degree to be considered in any "office" job. Hence - someone who only has (as you say) a short tertiary education will be at a significant disadvantage if they want to seek a career in an office-based job. So - yes - they'll be worse off compared to journalists, teachers, pharmacists, accountancy clerks, etc.
Since it's me who would give both the safe job and the short tertiary education, I really don't see the point of stating «the problem is that "people look for post-qualification service"».
The thing is that no-one will believe you when you say the job is safe. Combine this with a poor (by Polish standards) education, and you're simply not going to attract people who will be capable of learning a language and working in it within a year. Anyone who is in any way capable will simply not be interested in working for you, unless they can't actually afford to educate themselves.
Looking back at that thread I can see that delphiandomine stated quite clearly that you would not be «comfortable» with living in cities like Poznan if you wouldn't make 10-12000 PLN gross per month (I guess his statements are just part of the old adage that Poland is booooming).
Being comfortable for a foreigner has little to no relation to the expectations of young graduates in Poland. And 12000 gross a month is still only around 7500PLN netto - which for a foreigner expecting a good life of wining and dining, is really not that much money.
What you're proposing is perfectly fine for a young graduate, however. You won't get the best, but then it's not a job for the best really, is it?
2700 gross sounds good.
But you do realise that salary isn't the be-all and end all in Poland? Many young people are looking specifically for an employer who will offer a permanent work contract - and these are a licence for employees to screw over employers.
perhaps I'd be better off recruiting people from the West Pomeranian Voivodeship to come move to Gdansk for employment
Anyone who is in any way capable will already be in the big cities.
How would you rank those when it comes to expences?
Szczecin will be cheaper than the rest. Poznan and Gdansk will be more or less equal (though unemployment is only 4% in Poznan) and Krakow will be more expensive. You'll also have considerable opposition in Krakow when it comes to recruitment.
If you're ever in Poznan, give me a shout and I'll be happy to go over all this stuff with you (about contracts, in particular - these are a minefield) :)
