今天正好路過，解釋一下：

 "involuntary separation" is a vague statement, which means either laid off or fired. Most of the employers these days in order to avoid lawsuits, unwilling to say this person in fact gets fired. 

if someone gets laid off, the fault is on his/her employer, fired, him/herself. The consequences are different, the former is light, the latter severe. 

when it says involuntary separation, the company basically washes their hands, unwilling to point out whose fault it may lay on. Another thing, these days when doing a background check, many companies only confirm the employment date but nothing else for the same logic.
