The results show that body`s neutral position makes up 61.7% workers` working time. Body`s neutral position accounts for 57% of body posture in foundation, 55% in carcass, and 63.8 % in finishing stage. In other words, most body`s neutral positions were observed in foundation. Gentle bending posture was reported 21.2%. This posture was mainly observed in carcass stage. Severe bending posture was 8.2%. This posture was significantly less in other two stages.

"One leg in the air posture" accounted for the highest frequency in finishing (20.5%). "Kneeling posture" was reported higher in foundation than other two postures (14.4%). On the other hand, "neutral posture of foot" was the highest in all three stages compared to other postures (51.5%). "One leg in the air posture" accounted for the lowest frequency (2.0%). Table 4 shows the hand-related results. Although "both hands below shoulder level" posture was the highest frequency compared to other postures, it was significantly higher in foundation (87%). It was the lowest in carcass (78.5%). "One hand above shoulder level" posture was of the lowest frequency in foundation (8.9%). "Both hands below shoulder level" was of the highest frequency in carcass (9.5%). Generally, "Both hands below shoulder level" had the lowest frequency
