A friend has just been notified that her job has ceased to exist (due to cutbacks because of coronavirus). She was still in her probationary period and her employer has told her she hasn't passed probation, but has also implied that the job role no longer exists (ie this should be a redundancy matter). She has received no notice (presumably on the basis of failure to pass the probationary period) and has been let go with immediate effect. Is this legal?
