Production at a Fiat Chrysler Automobiles (NYSE:FCAU) factory in Ontario has been halted after workers refused to work because of coronavirus fears. 

As first reported by Automotive News, workers represented by Canadian labor union Unifor began a work refusal at FCA's assembly plant in Windsor, Ontario, late on Thursday. The refusal began after a plant employee chose to self-quarantine following contact with a person who has been tested for the COVID-19 virus. 

There are no confirmed cases of COVID-19 at the Windsor factory as of mid-day on Friday.

Separately, the United Auto Workers is in negotiations with FCA over compensation for employees who may be quarantined while being tested for the virus. The union represents FCA's hourly workers in the United States. The union raised the issue after a worker at an FCA transmission factory in Kokomo, Indiana, tested positive for the virus earlier this week.

The UAW's most recent contracts with FCA and the other Detroit automakers don't directly address the quarantine issue. General Motors (NYSE:GM) CEO Mary Barra said in a letter to employees oh Friday that all GM workers, including those represented by the union, will receive paid leave if needed because of the coronavirus.
