Wage is main issue both workers and new workers because it is their means of living. Income inequality by wage differential is reason of conflict of trade union-employer and worker-worker and generates social cost to solve the conflict. This paper finds wage differential factors of skill workers based on the case of welders and electricians and suggests the alternative ways to reduce the wage gap between welders and electrians. Resultingly, the reason of wage differential of two occupations is more non-human factors than human factors. Human factor is interpretation of architectural designs and understanding ability for them. Non-human factors are various; first possession of multi-skills, second difference of skill system, third riskiness of working environment, fourth pay ability by size of corporate, fifth supply-demand of workers, sixth substitute worker, seventh wage of market, last bargaining power. Alternatives to reduce wage differential are as follows; first rating system of skill by sector council in construction site, second career record system by electromagnetic card, third activation of labor-management cooperation job training, fourth practical unit price sheet for labor-cost, last supervision of management by government.
