It's the jobs, stupid. The American economy needs far more of them to help our society's high number of jobless get back to fiscal health and boost our overall economic health and productivity. The companies that have slashed significant percentages of their workforces over recent years haven't helped us at all. They've "helped" further bust our economy just when it's needed a boost.

Fortunately, some corporations are acting as economy boosters despite the tough times, hiring more workers and even implementing "no layoff" policies. Let's take a look at some of these companies, which challenge the conventional wisdom about difficult times.

Growing the ranks
Fortune's 2012 "Best Companies to Work For" list focuses on worker well-being and company perks, but it reveals some other interesting factors, too. Some of these companies are actually hiring.

  • Google (Nasdaq: GOOG) came in at No. 1, but the list highlights the search giant's 33% job growth, boasting a total 18,500 U.S. employees.
  • Darden Restaurants (NYSE: DRI) has racked up a 12% increase in jobs, with a whopping 169,516 U.S. employees.
  • Sunnyvale, Calif.'s NetApp (Nasdaq: NTAP), which provides networked storage solutions, has boosted its workforce by 30% to a total of 6,887 U.S. employees.
  • Amazon.com's (Nasdaq: AMZN) subsidiary Zappos has seen a whopping 70% jump in the number of people it employs, with its current U.S. worker count at 3,003.

Keeping the ranks
The last several years' tough economic times have been replete with mass layoffs, helping our unemployment problem become even more bleak in a vicious circle of joblessness. Unfortunately, many investors adhere to Wall Street's conventional wisdom: Layoffs boost profits.

True long-term investors will recognize that this is just a short-term boost, and this kind of behavior is actually very detrimental to the economy, and often to the companies themselves in the future.

Granted, in some cases, companies are in so much financial trouble they have to implement layoffs to survive at all. However, in too many cases, the companies in question are just working to assuage Wall Street analysts' short-term profit expectations.

Common sense says that with innovation, prudence, smart growth plans, and laser focus on long-term goals, companies can keep employees on board and never sacrifice long-term profitability.

Fortune highlighted 14 employers that have never laid off workers, illustrating that it's not an impossible task:

  • Private (and expanding) grocer Wegmans has a policy to find employees new jobs within the company if their positions are eliminated.
  • Retailer The Container Store found other ways to cut costs, right down to using cheaper toilet paper, to make sure it wouldn't have to lay off employees.
  • Even nonprofits must make ends meet. Instead of laying off employees, St. Jude's Children's Research Hospital ratcheted back hiring ("smart growth") and asked employees to figure out even small ways to reduce costs (such as cutting magazine subscriptions), showing that even the smallest sacrifices can add up to keeping everyone employed.
  • Aflac (NYSE: AFL) has been around for nearly 60 years, but it also made the no-layoffs list. Emphasizing employee education and cross-training, the insurer works hard to find workers another job in another part of the company when a position is eliminated.

The boosters vs. the busters
As investors, we can look at the aforementioned companies and examples to consider two things. One is the true nature of long-term-growth-oriented companies: Not only do they boost our economy, but they boost our portfolios and the promise of investing in myriad ways.

You can make money by your direct investments in Google and Amazon.com, for example, but their businesses both employ many Americans, giving them the means for growing consumption. They also contribute to a massive ecosystem of commerce, touching many areas, that helps keep our engine running. More consumer activity is good for all investors.

The other is the fact that management teams that can utilize smart growth in order to keep their workforces intact and running smoothly and productively are an economic boon. I've long believed investors should look at mass layoffs as signs of serious management flaws instead of focusing on a "more profitable" short-term view.

Once we've gotten five years down the road, many of these layoff-happy companies will have likely lost their best talent and terrorized and demoralized their "survivors." Those are dangerous stocks to own, Fools.

Don't let your portfolio go bust; remember that layoffs should be a sign of management weakness, not strength. Invest in the growth-oriented companies that act as economic boosters if you want to foster a growing portfolio.
