Transit operators
Area of Science:
- Occupational Health
- Transportation Safety
- Workplace Psychology
Background:
- Workplace violence and stress are significant concerns in public transit.
- Understanding factors influencing transit operator turnover is crucial for service stability.
Purpose of the Study:
- To examine the relationship between transit operators' risk perceptions of workplace drug incidents, occupational stress, job satisfaction, and their intent to leave their jobs.
- To identify key drivers of turnover intention among transit operators.
Main Methods:
- A cross-sectional survey was administered to 273 transit operators in Washington and Oregon.
- Data collected included perceived risk of drug exposures, occupational stress, job satisfaction, and intent to leave.
- Ordinal logistic regression models were used to analyze the associations.
Main Results:
- Higher perceived risk of workplace drug incidents was positively associated with increased intent to leave.
- Occupational stress and job satisfaction moderated the relationship between perceived risk and intent to leave.
- Elevated stress levels and lower job satisfaction were independently linked to a greater likelihood of intending to leave.
Conclusions:
- Interventions aimed at reducing perceived risks of drug use, such as enhanced training, may decrease turnover.
- Implementing support systems, including mental health resources, can mitigate stress and improve job satisfaction, thereby reducing operator turnover.
- Addressing risk perceptions and improving working conditions are key to retaining transit operators.
