Is it permissible to pray in advance when work commitments prevent me from praying on time?

My problem is that I cannot really pray on time. I live in Europe and I have to be at work at 8:30. I don't have a car and the company is quite far from the city center where there is a mosquee. The evening I live my job at 18h and I arrive at home at 19h. So I miss 3 prayers. So the only prayer I can do on time is the dawn's and the night's. Is it possible to pray by advance? What should I do in my situation?
