The New York workforce is incredibly diverse, ranging across sectors such as educational and health services, professional and building services, hospitality, construction, utilities, and others. Workers in a variety of occupations may encounter chemicals, physical hazards, as well as mental stressors that may cause health problems. 

We are studying workers’ health to better understand the impacts on the health of the workers who responded to the World Trade Center disaster as well as the COVID-19 pandemic. To find out if you are eligible to participate in the study, begin the survey below:
