As a Polish saying goes: "It's a bad bird who !!!!s in its own nest", so I really shouldn't make any comments on my company.
We do have resources to simulate these changes, unfortunately my unit is considered rather small by the management ( the "you only have two flights a day" kind of approach). Had it been Warsaw or ACC - the ATC staff would have been practicing few weeks before now.
I do agree that it doesn't sound very professional to admit that there are not going to be any simulation sessions. The reason for my post was that I believe that my responsibilty as an ATCO doesn't end at the end of the shift.
Don't worry about the safey level in Poland: vast majority of us have the same approach as I have; don't blame us if the system doesn't work as perfect as a dream.
