An EVP is usually written as a short internal statement backed by a few pillars, such as pay and benefits, career development, flexibility, culture and mission. It is built from research: employee surveys, exit interviews and conversations with recent hires about why they joined and stayed. A logistics firm might lead on shift choice and quick promotion to supervisor, while a charity might lead on purpose.
The EVP gives recruitment marketing, job adverts and screening conversations a consistent message to draw on. It only works if it is true, because people who join on a promise that does not match reality tend to leave early. Teams can test it by checking whether the claims in job adverts match what employees say, and by asking new starters whether the job matched what they were told.
