Employers in San Francisco, Los Angeles and other U.S. cities in recent months have been adjusting to fair scheduling laws sometimes referred to as “predictive” or “predictable” scheduling.

The laws can prove costly for businesses making last-minute scheduling changes to ensure there are enough employees on stand-by to cover shifts.

According to Ari Hersher an employment lawyer and partner in the San Francisco office of law firm Seyfarth Shaw “these are well-intentioned laws; however, there have been unintended negative consequences for the business community.”
