A protesting worker talks on his mobile phone as he sits in a tent in front of Tofas car plant in Bursa, Turkey, May 21, 2015. Industrial action over working conditions and pay in the Turkish auto industry has spread to a number of parts suppliers clustered around the northwestern city of Bursa. Production at two auto makers, Oyak Renault and Tofas, which account for more than 40 percent of Turkey's annual vehicle production, was halted earlier this week due to demands for better working conditions.
