You can also do this with Criteria API In clause as below:

CriteriaBuilder cb = entityManager.getCriteriaBuilder();
CriteriaQuery cq = cb.createQuery(Employee.class);
Root root = cq.from(Employee.class);
List parentList = Arrays.asList("John", "Raj");
In in = cb.in(root.get(Employee_parent));
parentList.forEach(p -> in.value(p));

return entityManager
        .createQuery(cq.select(root)
        .where(in).orderBy(cb.asc(root.get(Employee_.Parent)))
        .getResultList();
