Purpose The purpose of this paper is to investigate the job satisfaction level of quantity surveyors (QSs); identify the personal characteristics that influence their job satisfaction; and provide recommendations to employers on how to enhance job satisfaction of QSs with different personal characteristics. Design/methodology/approach Data were collected via a self-administered questionnaire to QSs in Singapore. Findings QSs feel that they have significantly high passion for the job, are significantly satisfied with task variety and are treated fairly. However, they are significantly dissatisfied with their workload, hours worked, and lack of work-life balance. QSs in upper management have significantly higher job passion. Those in mid-management are more dissatisfied with their income. QSs who are married/attached, older, and more experienced are significantly more dissatisfied with their workload and hours worked than singles, younger, and less experienced QSs. Research limitations/implications Some dimensions of job satisfaction were not measured. Non-personal characteristics such as type of projects handled and type of clients were not investigated. Practical implications Employers should investigate what goes into QSs' workload, and weed out those that are of low value and unproductive in order to reduce their workload and hours worked, and thereby increase their job satisfaction. Social implications The study contributes to human resource management by identifying the type of QSs who are more likely to be dissatisfied with their jobs. Originality/value This study shows that personal differences of QSs affect different dimensions of their job satisfaction. To maximize job satisfaction, employers could choose QSs who have specific characteristics, make changes to the work environment or redesign their jobs.
