Something like this? You don't need IDs in the Visualforce unless you do some JavaScript magic. This can be done completely in Apex.

public void updateRole(){
    List<Employee__c> toUpdate = new List<Employee__c>();
    for(wrapEmployee wrap : wrapEmployeeList){
        if(wrap.selected){
            wrap.emp.Role__c = SelectedValue;
            // wrap.selected = false; // you could choose to untick checkboxes now?
            // or after successful update loop through them one more time and then untick
            toUpdate.add(wrap.emp);
        }
    }
    update toUpdate;
}
