摘要：Duties and responsibilities must be accompanied with discipline, work passion and work achievement, where productivity at work is measurable and can potentially boost company’s profitability in the future. The aim of this research is to investigate the influence of discipline, work passion and work achievement on labor’s productivity in the City of Medan. The results of the research found that the variables of discipline and work passion failed to show an optimal result whereas the variables of work achievement and labor’s productivity show an optimal result. The analysis on discipline partially does not provide positive and significant influence on labor’s productivity at the company but causes loss for the company. The analysis on work passion partially does not provide positive and significant influence on work productivity at the company but causes loss for the company. An analysis on work achievement partially provides positive and significant influence on work productivity in the company and causes an advantage for company when workers show good work achievement, by which 45.7% of work achievement is very expected. The analysis on independent variables of discipline, work passion and work achievement discovered simultaneous influence on labor’s productivity.Duties and responsibilities must be accompanied with discipline, work passion and work achievement, where productivity at work is measurable and can potentially boost company’s profitability in the future.
