I have been working for a company for 6 months. On the first day of my employment my manager gave his four weeks notice. He set objectives and meetings in a document before leaving and left the duty to the interim manager while we were waiting for a new manager to be appointed. In the meantime the interim manager did nothing to assess my work and we didn't do any meeting to see whether I was doing good or not. A new line manager was finally appointed in the last 5 weeks of my probation, and he decided to extend my probation for further two months because he is basically not sure if I am fit for the job. I spoke with the higher level manager and they said that this is just a formality and to give the new manager more security about me, and I need to be really bad in this two months do be dismissed (I totally exclude this).
Now, in the worst case scenario, what if this new manager at the end of these two months decided to terminate my employment. Could a manager (himself still in a probation period) take such an important decision in such a short time he is in a company? Do I have some right to appeal to this potential decision because the interim manager did not assess me within the probation? I was doing good, he had a lot to do and since everyone was happy with my work, he forgot I was in my probation.
