Through the annual EmployerOne surveys which were conducted by the Four County Labour Market Planning Board between 2015 and 2020, employers shared their experiences with hiring and separations, hard-to-fill positions, recruitment methods and availability of workers. In addition to the following Executive Summary, the five reports in this series highlight the specific experiences of employers in Agriculture, Construction, Retail Trade, Healthcare and Social Assistance, and Manufacturing. These top five employment sectors in Bruce, Grey, Huron and Perth counties give us key information concerning how the local labour market has developed over time. The detailed reports on each sector are below. The EmployerOne Sector Review Executive Summary highlights key similarities and differences between these sectors based on EmployerOne findings. This will help establish a baseline for understanding employer experiences before COVID-19 and the associated disruptions to the labour market that began in March 2020 and, at the time of this writing, had not yet stabilized.
