<human>: So yeah,

I was sent a link by my friend who is unemployed and found a posting for my EXACT job. Same company, same title position (of which I am the only one to hold that title within the company), job description and my bosses email is the contact info. 

In my country (not US or Canada) he is legally allowed fire me without cause for the first year of employment. I am here 9 months. I am not looking for legal advise, I already got it and I actually can't prevent it from happening. I am certain he is abusing the law to avoid salary increase.

I am going to get fired, for no reason, yes I make mistakes at work (who doesn't?) but its not more than anyone else or as bad as anyone else, but he will list the petty human errors as the reason when the time comes and paint me as incompetent/unfit to the CEO or others within the higher levels of the company to justify it.  

I have not contacted anyone in the company yet (CEO or boss in question) about this. So advise on how/if to approach this with boss or CEO would be amazing. 

But mostly; How do I navigate it with my head held high and my dignity intact?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: gonna get fired, found my job posted online. How do I handle this information at work and with the people involved and remain a professional?
