I’m trying to make a simple program to build a work schedule, and I can’t get the data correctly. when I try to get employee

@Entity
@Data
@Builder
@AllArgsConstructor
@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<Shift> workedShift= new HashSet<>();

    public String getFullName() {
        return firstName+" "+lastName;
    }
    public void setFullName(String firstName, String lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }
    @Override
    public String toString() {
        return "Employee{" +
                "id=" + id +
                ", firstName='" + firstName + ''' +
                ", lastName='" + lastName + ''' +
                ", rate=" + rate +
                ", typeOfContract=" + typeOfContract +
                ", specialization='" + specialization + ''' +
                ", dateOfBirthday=" + dateOfBirthday +
                ", PESEL='" + PESEL + ''' +
                ", ZUSindex='" + ZUSindex + ''' +"}";
    }
}

from the database, the field worked shift is empty, in turn, when I try to get the class shift

@Entity
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class Shift implements Comparable<Shift>{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    private String station;
    private LocalDate date;
    private String startTime;
    private String endTime;
    private String actualStartTime;
    private String actualEndTime;
    @ManyToOne
    Employee employee;

    public HoursClass getWorkedTime() {
        if (this.actualStartTime == null || this.actualEndTime == null) {
            return null; 
        }

        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm");
        LocalTime localStartTime = LocalTime.parse(this.actualStartTime, formatter);
        LocalTime localEndTime = LocalTime.parse(this.actualEndTime, formatter);
        Duration duration;

        if (localEndTime.isBefore(localStartTime)) {
            duration = Duration.between(localStartTime, LocalTime.MAX).plus(Duration.between(LocalTime.MIN, localEndTime));
        } else {
            duration = Duration.between(localStartTime, localEndTime);
        }

        long totalMinutes = duration.toMinutes();
        int hours = (int) (totalMinutes / 60);
        int minutes = (int) (totalMinutes % 60);

        return new HoursClass(hours, minutes);
    }

    @Override
    public int compareTo(Shift o) {
        return 0;
    }

    @Override
    public String toString() {
        return "Shift{" +
                "id=" + id +
                ", station='" + station + ''' +
                ", date=" + date +
                ", startTime='" + startTime + ''' +
                ", endTime='" + endTime + ''' +
                ", actualStartTime='" + actualStartTime + ''' +
                ", actualEndTime='" + actualEndTime + ''' +
                ", employee=" + employee +
                '}';
    }
}

from the database, the employee field is filled with data correctly, I tried to get data from the database both using the findAll() method, which provides us with the JPA interface, and using the custom method

public interface EmployeeRepository extends JpaRepository<Employee,Long> {

    ///**
    //* 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<Employee> 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);
}

. Here is actually my class, in which I deal directly with the problem

@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<Shift> 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 alln");

        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"));
    }
}

here I save the data to the database, and then actually retrieve it, I also observe the problem when I manipulate the data through controllers.
this is what the database looks like after filling it with data

[shift table](https://i.sstatic.net/26KW7O4M.png) 
[employee table](https://i.sstatic.net/mhdSRqDs.png)

, and this is the log that the console shows directly after running the class

I use h2 database

I tried to change the order of adding objects to the database, I checked two codes (working and not working), retrieved objects in different ways, removed and added annotations to entity classes

I expect that when receiving an employee from the database, the work shifts field will be filled with the appropriate values
