Well I still have no better explanation than danya's here. 'UNqualified worK-FORCE' is quite an established term in the field. There are 3 versions: 1) unk as a typo for 'work' (I exclude it) 2) 'unk-unks' (AE slang) meaning unexperted troubles and used here as just 'unk' (have strong doubts about it now) 3) 'unk' as shortened 'unqualified'/ '[UNqualified worK]-FORCE' (thanx, Jo) - the best so far & fits the context.
To: Kenneth here is the source. It was in the Russian textbook for economists - a set of isolated sentences on the topic (taken from random sources as far as I can suppose from experience). The term could have been used in some newspaper article. Source country - unk :) (unknown, of course).
