This research, which conducted among construction workers aims to reveal the relationship betweenjob satisfaction and job security perception and the level of this relationship. Questionnaire method is used to determine jobsatisfaction and occupational safety perception of the employees and 161 construction workers were interviewed face to face.The questionnaire consists of 3 sections.

Inthe second part, Minnesota Job Satisfaction Scale, which is used to determine the level of job satisfaction is given.
