Officials in charge of the province's largest health-care facilities say the proposed values charter will wreak havoc on the system.
The Quebec Association of Health and Social Service Establishments has asked that the health sector be exempted from Bill 60.
It would ban state workers from wearing large religious symbols on the job.
The association says it deeply disagrees with the government's desire to prevent its employees from displaying their faith.
The administration predicts the bill would have a profoundly negative impact on its workforce, which it says is already stretched thin.
The association represents more than a hundred establishments, employing more than 200-thousand people.
