In the US, effective January 2007, the Pension Protection Act of 2006 allows traditional pension plans to pay retirement benefits to workers at least aged 62 while still working. Some believe this may encourage older employees to work longer to ease the labor shortage caused by retiring baby boomers. However, many of those continuing to work would be part-timers. So, filling the gap of an impending labor shortage requires drawing workers from people of any age. A human resource strategy of flexible work options for all ages could help generate more workers.
