Assuming the employee is otherwise qualified to hold elective office, Washington State does not have a “resign to run” law, so there is no bar for a current employee to run for city council. However, it is a separate question what happens if they win (or wish to be appointed to a vacancy).
If a current staff member were to win a council seat, they would then have to consider whether continued employment with the city would be a financial conflict of interest. See MRSC’s page on Ethics and Conflicts of Interest. Any renewal of collective bargaining agreements or employment contracts or other pay or benefits increases would likely give rise to an unavoidable conflict of interest. Note, however, that there are exceptions for municipal officers serving in jurisdictions below a certain size where the value of the contract is below a certain dollar threshold. See RCW 42.23.030(6).
Even without the financial conflict of interest, it also becomes a blurred line of authority for a councilmember to have to answer to the mayor as an employee.
If one of the city’s employees does win a council seat, the city attorney will need to provide legal advice about the specific situation.
