  It is hard to establish whether a company supports internal sustainability
efforts (ISEs) like gender equality, diversity, and general staff welfare, not
least because of lack of methodologies operationalizing these internal
sustainability practices, and of data honestly documenting such efforts. We
developed and validated a six-dimension framework reflecting Internal
Sustainability Efforts (ISEs), gathered more than 350K employee reviews of 104
major companies across the whole US for the (2008-2020) years, and developed a
deep-learning framework scoring these reviews in terms of the six ISEs.
Commitment to ISEs manifested itself at micro-level -- companies scoring high
in ISEs enjoyed high stock growth. This new conceptualization of ISEs offers
both theoretical implications for the literature in corporate sustainability,
and practical implications for companies and policymakers. To further explore
these implications, researchers need to add potentially missing ISEs, to do so
for more companies, and establish the causal relationship between company
success and ISEs.
