Don't despair about RTO - just mention "work from home" in every TTUS survey, and bring it up in every town hall. Gunjan hates being asked.
Don't pay any attention to Gunjan's criticisms and meanness - just leave reviews on Glassdoor and mention her by name.
Don't hate your job - make Gunjan hate hers.
Don't hate your life - make Gunjan hate hers.
