This study aims to assess validity of Turkish version of Multidimensional Work Ethic Profile (MWEP). In 2007, MWEP has been used as an international scale to measure work ethic in English, Spanish and Korean cultures. Examining its validity in Turkish culture helps to discern its extent of generality and comprehensiveness. Sample group consisted of 312 employers, senior and intermediate level managers and freelance employees who were working in commercial and industrial SMEs, large bureaucratic and network enterprises in Istanbul, economic capital of Turkey. Results of Factor analysis indicated that Turkish version of MWEP didn't exactly measure all work-ethic dimensions proposed by Miller et al. (2002). Further analyses reavealed that 9 items of 10 in 'Leasure' dimension, only 5 items of 10 in 'Centrality of work', 'Morality/Ethics', 'Self-Relaince' dimensions measured the same dimensions of English version of MWEP scale.
