Criminal history of an employee is public information or records and it is not confidential, even when a criminal record is expunged the information is available to government agencies, so that really is not actionable. However, what is actionable is the supervisor harassing you for no reason. The statement you claim your supervisor made that they do not feel safe is the common cry of people today, as they have thin skins and know if they claim they feel threatened or unsafe that action will be taken and today people feel unsafe when someone sneezes or even looks in their direction, so these claims are becoming more and more viewed as frivolous by the courts.
As far as your civil service protection,the employee is protected from frivolous complaints or from having action taken against them for no reason and without any actual evidence of a violation. This supervisor making false or frivolous claims they are afraid or feel unsafe because of their own mental health or emotional instability issues does not mean that it is true. So your union is right about filing the grievance against her, but in addition to filing the grievance, you can also consider suing this thin skinned individual for defamation, harassment and intentional infliction of emotional distress for their conduct towards you based on known false statements and for no reason other than to harass you and cause you emotional distress. Sometimes that is all these types of people understand, being pulled into court and made to spend money to defend their silly actions.
