Really. What kind of job fires you for having a score under 700, even briefly? And if it was briefly, how did they know? Did they check your score every month? I'm not saying I don't believe you, because I do. But it just seems extremely ridiculous.
And how can they justify that? Everything I've ever read or been told says that even between 600 and 700 is "good".
Sounds like you might have had a case for a wrongful termination lawsuit.
I can't think of any job that would have a requirement to have a credit score of over 700, at all times. WTF.
