As previously discussed, a probation period enables an employer to terminate the contract of an employee who is not performing to the expected standard within their new job/role or is otherwise deemed not suitable for the particular job/role.
Whether or not this empowers employers to abuse their employees by, without warning, terminating their contract before the probation period has ended is open for debate.
To this end some organisations, to avoid the potential issues arising from the termination of a new employee, are waiving the probation period entirely.
Instead, these organisations are conducting multiple interviews of the new employee, under a variety of conditions and over a period of time, before making the final decision to hire.
