You should use this letter when an employee has successfully passed their probation period and you want to confirm their employment with your business. Ideally, you should have informed the employee that their probation period has ended during their probation review meeting. As a follow-up, this letter should be utilised. It merely states in writing your decision that the employee has successfully completed their probation period, and it is the final step in confirming their appointment to their employment post. Most job offers are contingent on the successful completion of a brief probationary term. This period allows you, as the employer, to observe how the person works and whether they are a suitable fit for your company. Similarly, they allow employees to take some time adjusting to their new role before fully committing to it. Upon passing their probation period, employees will be eligible for your business benefits.
