        if (selectedDate?.filter((e: any) => e.employeeId === employeeId).length > 0) {

            setSelectedDate(selectedDate.map((e: any) => {

                if (e.employeeId === employeeId) {

                    return { ...e, workAnniversary: value }

                }

                else {

                    return { ...e }

                }

            }))

        }



        else {

            setSelectedDate([...selectedDate, { employeeId: employeeId, workAnniversary: value }])
