2.11 Multi-layer of sub-contracting system

The nature of Hong Kong building industry is its farm outing system. Main contractor involve employ to hold many trades sub-contractor together for development of edifice. For illustration: Laying and hardening of concrete, bending and repair of steel support saloon, hard-on of lumber formwork, and stick oning work, etc. , The ground is that the chief contractor can non set about different types of proficient work and much hard currency flow at the same clip.

But employers frequently said the advancement is really tight of building. It causes frequently neglect the importance of security, taking many workers to accidents. Employees when unsafe environments appear, they should instantly halt all the work and advise the employer to better the unsafe environment. If the employer failed to better the unsafe work so employees should be instantly inform relevant authorities sections to cover with this job.
