はshowアクション

@employee = Employee.find(params[:id]) 
@employee_skill = @employee.employee_skills.new 
# The above statement will set :employee_id with employee's id 

にEmployeeSkillのインスタンスを初期化し、そのが正しく生成されない場合は、明示的:urlを渡すことができる形式で

<%= form_for([@employee, @employee_skill]) do |f| %> 

をそれを使用します

<%= form_for([@employee, @employee_skill], url: employee_employee_skills_path(@employee)) do |f| %>
