Immaterial frivolous or not. He's suing for 4-6 months salary and benefits. $75,000. Doesn't even explain how he arrived at that peanut amount. It looks like he has fired 1.5 months earlier than expected according to the details and he makes $10,000 per month.
So $15,000 salary + $60,000 lawyers probably threw in there because that's what lawyers do. Even the full amount, if it was 100% legit, is immaterial.
