Since the fall of the Wall, a new iron curtain - that of wages - has stretched across Europe. Every year, hundreds of thousands of workers from Eastern Europe, lured by wages three times higher than in their home countries, cross the continent in search of demanding, low-skilled jobs. Leaving Prague, Czech journalist Sasa Uhlova experiences the reality of these precarious jobs in the shoes of economic migrants essential to Western Europe's prosperity. In Germany, on a vast fruit and vegetable farm alongside Polish immigrants, in an Irish hotel in the company of Slovakian colleagues, then as a care assistant in Marseille, she experiences physical pain, stress, fatigue and hellish work rates.
