By word-of-mouth from an HR insider. Apologies if I mess up the terminology.
If you are a US-employee and both of these apply to you:
IR or SSL4/5 in 2015 focal.
IR or BE or SSL4/5 in 2012/2013/2014 focal.
Then your last day will be July 15 and you are never eligible for rehire.
IR = improvement required
BE = below expectations (no longer used)
SSL = stock share level (there are 5 levels: 1 is best, 5 is worst)
focal = Intel's performance review process
