I quit a job and they put dismissed on my roe what can i do

Ultimately this will likely not impact you because if you quit, you would not be entitled to any Employment Insurance (EI) benefits anyways. If you were dismissed, and they note "dismissed" on your ROE, you could potentially be eligible for EI benefits. However, they might make inquiries with your employer, and indicating 'dismissal' on the ROE may have been an inadvertent mistake on their end.

Potential employers will not be able to access your ROE. However, if you are concerned about the ROE saying 'dismissal" in the rare chance that a prospective employer asks to see it, you should reach out to the company to ask them to revise it.
