“Over time, coverage reductions inevitably would make the workers that employers most want to keep worse off, and if those workers sought employment elsewhere as a result, then the firm would be worse off as well,” the think tank said in a recent report.

About 45% of American workers get health care through an employer. PPACA wasn't intended to displace employer-provided health care, of course, though critics and others have suggested it will.

They point to such highly-publicized cases as the announcement by Sweden-based Securitas, a global security company, to discontinue it mini-med plans for workers in Ohio. Darden Restaurants, Home Depot and Trader Joe's also have announced that they would shift employees to Obamacare exchanges.

But those moves all involved part-timers. Also, mini-meds aren't the sort of bare-bones plans provided by most employers, and they're not typically seen in fields where compensation is better than in, say, the security or restaurant industries.

“Five years from now we are going have a functioning health insurance exchange system,” predicted Helen Levy, a research associate professor with the University of Michigan Institute for Social Research, Ford School of Public Policy and School of Public Health. “I think it is going to be a valuable option for people and I think we are going to say, 'I can't believe it was ever not this way.'”

But that's all it will be, she said, one of several options people will be able to turn to obtain health insurance.

Echoes of that sentiment can be found in research by the Congressional Budget Office, the Rand Corp. and others.

In fact, the number of employers that plan to continue providing employees with health insurance has increased, according to an International Foundation of Employee Benefit Plans survey.

Its “2013 Employer-Sponsored Health Care: ACA's Impact” survey addressed how employers are responding to changes unleashed by the law.

Nearly all (94%) of the 966 benefits and human resource professionals, general and financial managers, and other company officials who responded to the March survey said they “definitely” or “very likely” will continue providing health insurance coverage when many of the PPACA's provisions take effect in 2014, up from 86% who responded similarly in 2012.

A large majority (69%) responded they'd definitely continue providing coverage, up from the 46% who made the same claim in 2012.

In another survey, The Midwest Business Group on Health found 90% of employers had no plans to move workers to either public or private exchanges in the “immediate future.” Its survey, with responses from mostly large companies with more than 5,000 workers, did include a small number of employers with fewer than 500 workers. Just 4% of those respondents “anticipate moving either their part-time or retiree populations over to the public marketplace,” the organization said.

Bryce Williams, managing director of global benefits company Towers Watson Exchange Solutions, said most large companies made any big PPACA-related changes to their health insurance plan two years ago.

He told USA Today that only about one in 10 of the major companies Towers represents are making major changes to their health plans this year. Towers Watson represents about 80% of the companies on the Fortune 500, he said.

Of course, conflicting statements and predictions by many continue to dominate the headlines of mainstream media outlets and water-cooler conversations across the country.

Last month, for instance, Towers Watson shared a survey in which 98% of employers reported they will keep “active medical plans” for 2014 and 2015. In turn, the conservative Heritage Foundation took issue with that particular finding and stressed the same study found that 92% of employers said they'd likely change their health insurance options by 2018, the year the law's “Cadillac” tax on high-cost plans takes effect.

Changing options, however, isn't anywhere close to dropping coverage altogether.

And then there's the report from PricewaterhouseCoopers, which found that in Massachusetts, where the model for the federal plan took effect seven years ago, employer-sponsored coverage has actually increased.

“The number of people covered by insurance through the workplace increased by about 1 percentage point, running counter to the rest of the nation, which saw employer-based insurance decline by 5.7 percentage points,” according to the report.

PricewaterhouseCoopers found that Massachusetts's individual mandate had two unanticipated effects.

First, it led to a lot of employees signing up for employer-based coverage they'd previously rejected. Second, it led some workers to ask their employers for insurance. The study notes that “the percentage of small employers offering coverage in Massachusetts rose from 45% to 59% between 2005–2011,” even though insurance premiums actually rose for small employers.

According to a survey by the National Business Group on Health, many companies are, in fact, mulling over the idea of forcing retirees and part-time workers onto the exchanges after the PPACA takes hold.

For part-timers with insurance coverage – a very small share of the population – it's no doubt possible the federal subsidies available via the exchange will pencil out in their favor.

That might be true for some small-business owners, too, whom Levy pointed out have generally experienced a slight disadvantage when it comes to providing competitive benefits.

But, again, the consensus among nonpartisan observers is that larger employers aren't likely to drop coverage for their employees any time soon.

Beyond the recruitment and retention issues, large firms will face a penalty in 2015 if they don't offer insurance. There's also a penalty if they offer insurance but it's not considered affordable.

The Small Business Majority, an advocacy group, especially likes the law's health exchanges and tax credits for small businesses.

“The benefits far outweigh the costs,” John Arensmeyer, the group's founder and CEO, told Politico. “There's been a lot of confusion. … There's been more heat than light on the subject.”

One prominent economics instructor penned an op-ed in the Washington Post in hopes of adding more light.

David Cutler, a Harvard University economics professor, noted that PPACA has helped slow the annual increases seen in what Medicare pays to hospitals, home health agencies and private insurance plans.

“Many Americans are rightly upset with the Obama administration's rocky rollout of the insurance exchange,” Cutler wrote. “Failing at such a major project is inexcusable. But if the early indications are any guide, we should be pleased with how the new health law is affecting what we pay for care. If the Web site is fixed and enrollment can catch up to expectations, [PPACA] could yet become a major policy success.”
