The 2008 National Study of Employers (NSE) introduces factors which can predict flexibility and range of benefits. Size of company, number of union members, number of hourly employees and demographics of employees are examples of factors used as predictors. Employers that are nonprofits tend to offer the widest range of benefits for managing work and personal lives. Employers with more diversity in top positions and large employers also offer more support. Large companies are more likely to provide benefits which have direct costs, like child and elder care assistance.
