Integrity is the quality of being honest and having strong moral principles.
We rarely see it listed for requirements in job postings.
We rarely see it on resumes or written in performance reviews.
We rarely see it written in Employee Handbooks provided by companies.
People want to work for people that are creating a culture with moral principles.
It's not always easy to have integrity. Sometimes there is a risk to standing up for something because it is 'the right thing to do'.
Look for the ones with integrity.
