Ppl, always expect the worst. make a back up plan.
This way atleast you will have a chance for preventive or corrective necessery action. Now though I am April, 2002 filers, I am taking this notice seriously and planning for future steps. I will start looking for job in september/october (180 days over) and once I get a offer, I will ask my employer for huge raise. if not happen, quit.
* I know stupid moron like pateinceGC will start looking for some sorts of argument (if nothing there, at least with spell mistake..) but for other ppl, always prepare for the worst, you will not surprise.
