After my six month probation period with my current employer had expired, I was told that my probation period is being extended for three months. My original probation period was from 11 Nov to 11 April. In end of April, my manager told me about the extension. However, I was only told of the extension verbally by my manager; no-one asked me to sign anything, and I was not given any letter by our HR department.
At that time, my manager has told me that senior managers will perform a review and that I should keep looking for other jobs. And, my manager and TL told me this is all confidential, and I'm not suppose to talk with anybody about this (Otherwise i will be fired straightaway), which seemed strange.
How should I react to not receiving a written notice of the probation extension, and not being notified of the extension until after the initial period had expired?
