In the quest to retain workers, companies are sharpening their focus on a very specific common goal: 90 days.
Hold on to an employee for three months, executives and human-resources specialists say, and that person is more likely to remain employed longer-term, which they define as anywhere from a year on in today’s high-turnover environment. That has led manufacturing companies, restaurants, hotel operators and others to roll out special bonuses, stepped-up training and new programs to prevent new hires from quitting in their first three months on the job.
