You use

  if($model->save(false)){ 

this mean no validation are performed

try using

   if($model->save()){ 

and in actioCreate you should recall render create if model->save() fail

public function actionCreate()
{
    $model =  new Employee();

    if($model->load(Yii::$app->request->post())) {
        $model->company_id = $userModel->company_id;

        $model->employee_id = Yii::$app->request->post()['Employee']['employee_id'];

                $model->role_id = Yii::$app->request->post()['Employee']['role_id'];
                $model->report_to = Yii::$app->request->post()['Employee']['report_to'];
        // print_r(!$model->validate());die();
         if($model->save()){
            return $this->redirect(['view', 'id' => $model->id]);
         }
        else {
           return $this->render('create', [
            'model' => $model,
           ]);
       }
}

Try performing composer update, there was a Yii2 bug fixed that was tied to unique validator when using relational data in addition to other scenarios:
