공사현장의 이미지를 떠올렸을 때, 쉽게 생각할 수 있는 이미지 중에는 조적공사가 있습니다.
공사현장을 대표하는 이미지를 갖고 있으나 그 뒤에는 많은 사고 사례를 갖고있는 공종입니다. 작업대부터 시작하여 다양한 사고 사례가 있는데, 힘든 노동일을 전제로 하기 때문에 요즘은 거의 대부분 근로자가 외국인으로 이루어져 있습니다. 한국 사람은 찾기 힘들죠!!
자재값과 물량은 정해있으니, 인건비에서 아껴야 한다는 수입구조 때문입니다. 인건비를 아끼기 위해서는 1인당 소화해야하는 물량이 많아야 하구요. 그렇기 위해서는 업무 속도를 올려야합니다. 안전을 뒷전으로 넘기기 쉽게 되죠!!
안전하게 작업을 하고 싶어서 할 수 없는 구조… 뭔가 좋은 대책이 나왔으면 좋겠네요. 모두 상생할 수 있는 방법으로….
최근 요소수 부족현상 때문에 다들 걱정이 많네요. 잘 해결되었으면 하는 마음으로…. 일요일을 보냅니다.
감사합니다.
