Hibernate не загружает дочерний объект внутри родительского объекта ⇐ JAVA

Пытаюсь сделать простую программу для построения графика работы, но не могу правильно получить данные. когда я пытаюсь нанять сотрудника

@Builder

@NoArgsConstructor
public class Employee {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
private String firstName;
private String lastName;
private Double rate;
private TypeOfContract typeOfContract;
private String specialization;
private LocalDate dateOfBirthday;
private String PESEL;
private String ZUSindex;

@OneToMany(mappedBy = "employee", fetch = FetchType.EAGER)
Set workedShift= new HashSet();

public String getFullName() {
return firstName+" "+lastName;
}
public void setFullName(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}
@Override

}

из базы данных поле обработанной смены пустое, в свою очередь, когда я пытаюсь получить смену класса

}
}

из базы данных поле сотрудника заполнено корректно, я пробовал получить данные из базы как с помощью метода findAll(), который предоставляет нам JPA-интерфейс, так и с помощью собственный метод

Код: Выделить всё

public interface EmployeeRepository extends JpaRepository {

///**
//* Searching employee by id
//*
//* @param id of the searched employee
//* @return the searched employee
//*/
//@Query("select e from Employee e where e.id = :id")
//Employee getEmployeeById(Long id);
@Query("SELECT e FROM Employee e JOIN FETCH e.workedShift")
List  findAllWithShifts();
/**
* Searching employee by full name
*
* @param fullName of the searched employee
* @return the searched employee
*/
@Query("SELECT e FROM Employee e WHERE LOWER(CONCAT(e.firstName, ' ', e.lastName)) = lower(:fullName)")
Employee getEmployeeByFullName(String fullName);
/**
* Searching employee by PESEL
*
* @param pesel of the searched employee
* @return the searched employee
*/
@Query("SELECT e FROM Employee e WHERE e.PESEL = :pesel")
Employee getEmployeeByPESEL(String pesel);
}

. Вот собственно мой класс, на котором я непосредственно занимаюсь задачей
@Component
@AllArgsConstructor
public class BootStrap implements CommandLineRunner {

EmployeeRepository employeeRepository;
ShiftRepository shiftRepository;
EmployeeService employeeService;
ShiftServiceImpl shiftService;

@Override
public void run(String... args){
Employee employee = Employee.builder()
.firstName("Adam")
.lastName("Kowalski")
.PESEL("03947283728")
.rate(23.5)
.build();
Employee savedEmployee = employeeRepository.save(employee);

Stream randomShifts = Stream.generate(() -> {
return Shift.builder()
.station("Station " + (new Random().nextInt(10) + 1))
.date(LocalDate.of(2024,5,5))
.startTime("10:00")
.endTime("20:00")
.actualStartTime("10:00")
.actualEndTime("20:00")
.employee(savedEmployee)
.build();
}).limit(5);

shiftRepository.saveAll(randomShifts.collect(Collectors.toUnmodifiableSet()));

System.out.println("\n after save all\n");

System.out.println("\n All employees "+ employeeService.getAllEmployees());
System.out.println("\nsalary= "+employeeService.getMonthSalary(1L,5));
System.out.println("\ntax= "+employeeService.getMonthTax(1L,5));
System.out.println("\nRevenue= "+employeeService.getMonthRevenue(1L,5));

//employeeRepository.findAll().forEach(publisher -> System.out.println("\n"+publisher+" have "+publisher.getWorkedShift()));
employeeRepository.findAll().forEach(publisher -> System.out.println("\n"+publisher+" have "+publisher.getWorkedShift()));
shiftRepository.findAll().forEach(book -> System.out.println("\n"+book+ " have "+book.getEmployee()));

System.out.println();
System.out.println("\n all shift by employee 1"+shiftService.getAllShiftByEmployee(1L));
System.out.println();
System.out.println("\n employee with pesel"+employeeService.getEmployeeByPESEL("03947283728"));
}
}

здесь я сохраняю данные в базу данных, а затем фактически извлекаю их, также наблюдаю проблему, когда манипулирую данными через контроллеры.
так выглядит база данных после заполнения его данными

Я использую базу данных h2
Пытался изменить порядок добавления объектов в базу, проверил два кода (рабочий и неработающий), извлекал объекты разными способами, удалял и добавлял аннотации к классам сущностей
Ожидаю, что при получении сотрудника из базы поле "Рабочие смены" заполнится соответствующими значениями
