Appointment Letter for Casual Workers
The casual employment period cannot be taken into consideration anywhere. Whenever an employee has been appointed, only that date can be mentioned. After the issuance of the Offer of Employment, the probation period will be 6 months. Afterwards, you can issue the Appointment Letter, which will have the appointment date as ante-dated, i.e., from the joining date as permanent staff from day 1 of the probation period.
