3 months before expiration I had a performance review with my supervisor who spoke very highly of my achievements. However, to be fair, imho he is the kind of person who would praise even the worst performer. To my question of possible renewal he replied with "judging from this review, clearly, I want you to stay. I would give it a 90% probability it will be renewed, but you know, in this world you never have the job until the official letter has arrived".
Now it's 2 months left. I know they are looking for someone to replace my colleague who had to resign (he left to get a graduate degree). Am I right to start panicking?
