Is paid parental leave good for small business?

There's growing debate (and growing support) in the U.S. around paid parental leave. It's become a major campaign issue, and many states and municipalities are considering its pros, cons, and costs. For large private companies--think Google, Netflix, Adobe--expansive leave policies are a salary bargaining chip and a recruiting and retention tool.

There's growing evidence that parental leave policies are good for business. Google increased employee retention after it implemented a generous maternity leave policy, which improved the bottom line. Turnover is extremely costly for all sized businesses. But what does the growing debate mean for small business?
