Tysons; 36 employees
December can be a stressful time for anyone who works around Tysons and its two shopping malls. Cassaday has “early release” days around the holidays so staff can beat the traffic. The wealth-management firm invests in employee happiness in other ways—paid gym memberships, profit sharing, daily fruit platters, in-office massages. The result? A loyal workforce with an average tenure of ten years.
Perk: 26 paid days off after six years of service for people in management.
