Rehire

Ziri went in and asked the manager to rehire Rima.

There are many upsides to rehiring former employees, according to management professor Peter Cappelli of the University of Pennsylvania's Wharton School of Business. The positives include savings on recruiting and training costs, maintaining associations between customers and employees, and the fact that the rehired employee doesn't need an introduction to his or her colleagues.

The National Labor Relations Board petitioned in federal court to force Starbucks (SBUX) to rehire three workers who claimed the coffee chain retaliated against them for attempting to unionize.

Not all rehires have a happy ending. Jerry Abiog, 37, worked for an Atlanta-based consulting firm until he was laid off in January -- only to get called back six weeks later.
