The proposed charter would ban public sector employees from wearing overt religious symbols such as the hijab or kippas.
The charter was tabled in November, however the PQ has refused to specify what would happen if a worker refused to remove specified religious symbols.
But on Wednesday, in an interview with Montreal's 98.5 FM, Marois said a PQ government would help find new positions for civil servants who refuse to comply.
She said her government would find alternative options that matched the workers' skill sets.
Liberal Leader Philippe Couillard says that would force some Muslim women to choose between their jobs and their identities.
"For the first female premier to take such an unprecedented, discriminatory approach towards women is highly ironic," Couillard said.
