Proposed federal laws that could shore up health coverage will focus new attention on older workers. Employee incentives such as flexible schedules, and a lot of buzz, are creating an inviting atmosphere for longer work lives.

It could mean a second "encore" career, the way former President Clinton is now focused on poverty and AIDS, or extending a career.

A survey of 50- to 65-year-old workers done for the federal government in August found that 29 percent of 55- to 59-year-olds plan to work beyond 65.

Bob Haagenson will retire at 57, but he will not stop working.

He packed up his Sacramento, Calif., home recently and headed for a new four-bedroom home in the Corpus Christi, Texas, area. And a new job, as soon as he finds one.

Until a couple of weeks ago, he oversaw a $22 million budget as a chief administrator for Sacramento County's Finance Department. He has a 20-year military career behind him, along with nearly 14 years at the county. Why stop now?

"Even the Realtor said, 'Wow, you can get a job anywhere you want,' " Haagenson said.

He is checking help-wanted ads and the federal government Web site, but his main goal is to stay out of the house and off the sofa.

"I'd probably be happy handing out carts at Wal-Mart," he said.

Steve Sass of the Center for Retirement Research at Boston College is co-author of Working Longer, a book due out this month.

The golden age of retirement - with hefty private pensions, abundant medical insurance, and adequate Social Security at 65 - is disappearing as baby boomers reach the finish line, Sass said.

To ensure a retirement comparable to a generation ago, baby boomers will have had to save more or work longer, he said.

But there is good news, he said: "You don't have to work until you're 80."

Just working three or four years longer will boost Social Security benefits by a third, he said. Delaying 401(k) withdrawals should also offer similar boosts, Sass said.

He suggests that workers clearly convey their plans to employers if they intend to stick around.

"Maybe they'll invest in you, promote you," he said.

The timing could be fortuitous for longer work lives: Baby boomers are healthier and better-educated, Sass noted. And they are among the first to forge identities largely from their work.

That means workers in this generation treasure the trappings of work, such as social networks, and are reluctant to let go, said David Bank, who is vice president of Civic Ventures, a San Francisco nonprofit think tank promoting encore careers.

Where the employment sector was once designed to move workers into retirement, private and public employers are looking at how to retain or hire them, he said.

On the East Coast, retired Teamsters are still driving, but they are shuttling people to doctor appointments or other errands.

In New York, health clubs are hiring older physical-fitness trainers to work with older members.

The economy in general benefits if people work longer, because they continue to pay taxes and contribute to Social Security, Bank said.

"Our position is that a lot of things could be done to make it appealing and attractive," he said.

Embarking on encore careers is actually part of a larger trend, where workers change jobs several times in their career, Bank said. The lifetime job at one company is going the way of black-and-white television, he said.

Encore careers could be the chance for personally meaningful pursuits, Bank said, like the lawyer who retires to sell fishing rods part time, the bus driver who goes to work at a golf course, or the person who branches out into charitable efforts.

"People say, 'I've always dreamed of being a teacher or working in the environmental field,' " Bank said.

The employers most tuned in are in retail, Bank said. Many retail chains extend health benefits to part-timers, but the nonprofit sector - which could benefit from boomer retirees - is less receptive, he said.

"What we're saying," he said, "is that there should be the same benefits for teaching a child to read as for pouring coffee."
