A probationary contract is defined as a contract of employment which runs for not more than 6 months duration. Normally this employment is intended to see if the person is suitable for the role which has been prepared for them and the business itself. A person who performs satisfactorily during the probationary contract may earn themselves a longer contract with better conditions and remuneration. CAN PROBATION LAST LONGER THAN 6 MONTHS? Probationary contracts can only be extended beyond the limit of 6 months with the consent of theemployee and that extension cannot be for a period longer than 6 months. Additionally, an employee should not be employed on a probationary contract for more than one occasion.
