She didn't file a lawsuit. She filed a charge with the NLRB, the NLRB investigated for nearly for 21 months and has initiated a formal case (internal to the NLRB, not a lawsuit) against Mozilla.

There is almost certainly evidence cited in the NLRB complaint, but that complaint is non-public and subject to redactions before being released under the FOIA, and AFAICT no one has FOIA'd and published even the redacted version. But "I don't have access to the document where any evidence would be discussed" may technically make "from what I can see, there is no evidence" correct, the "from what I can see" is doing a lot of work.
