Just to clarify: was "fired without cause" (worked "at will" which most of full-time employments are in the US). By asking why they were getting rid of me I heard the pharse "for no good reason, really" like a broken record. This was enough indication that it was clearly in regards to my talk with HR a few days prior.

Also, during my announcement to HR about my wife's circumstances, I remarked I wanted to take some time off to be there for wifey & baby.

The company was 90% lawyers so just in case I wanted to proceed legal action against them, their Armada of lawyers made a possible follow-up rather unsavory.
