Today’s labor markets are undergoing radical change, as digital platforms transform how they operate and revolutionize the nature of work. In many ways, this is a positive development, one that has the potential to match workers with jobs more efficiently and transparently than ever before. But the increasing digitization of the labor market also has at least one very worrying drawback: it is undermining the traditional employer-employee relationships that have been the primary channel through which worker benefits and protections have been provided.

The ecosystem of digital labor platforms is still in its infancy, but it is developing rapidly. Large popular platforms like LinkedIn have so far mainly been used to match high-skill workers with high-end jobs. But these platforms are already expanding to accommodate middle-skill workers and jobs. Nearly 400 million people have posted their resumes on LinkedIn, and in 2014 the site facilitated more than one million new hires worldwide.

Meanwhile, other types of digital platforms are emerging, linking workers with customers or companies for specific tasks or services. Such platforms play a growing role in the market for “contingent” or “on-demand” workers, broadly defined as workers whose jobs are temporary and who do not have standard part-time or full-time contracts with employers. Well-known digital platforms that link contingent workers directly to customers include Lyft, TaskRabbit, Uber, and Angie’s List. and Upwork are examples of platforms that help companies find and hire contingent workers for a range of specialized tasks such as software or website development. has more than 17 million users worldwide.

The trouble is that even as these sites provide new opportunities for workers and companies, they are bypassing the traditional channels through which the US and many countries deliver benefits and protections to their workforce. In the US, in particular, the “social contract” has long relied on employers to deliver unemployment insurance, disability insurance, pensions and retirement plans, worker’s compensation for job-related injuries, paid time off, and protections under the Fair Labor Standards Act. Although the Affordable Care Act has made it easier for workers to acquire health insurance on their own, most workers continue to receive health insurance through their employers.

With the proliferation of digital job platforms, the social safety net for workers in the US – threadbare to begin with – is at risk of unraveling for a growing share of the workforce. This is because most individuals who find work through digital job platforms operate as independent contractors, leaving them without the benefits and protections provided in standard employment contracts for full-time and part-time workers. The difference between the cost of a full-time employee with benefits and an independent contractor can be 30% or more, so there is a strong incentive for companies to replace workers on standard full-time employment contracts with independent contractors as long as companies can attract the talent they need.

Digital job platforms also make it easier for businesses to hire and fire workers on temporary contingent contracts. This creates the potential for a race to the bottom, with employers competing on labor costs through regulatory arbitrage.

Unless policymakers act, the US will continue to drift toward a two-tier labor market. One tier will be populated by fully employed high-skill workers with generous employer-provided (and tax-advantaged) benefits, as well as high-skill individuals who finance their own benefits from high incomes earned as independent contractors or from self-employment. The other tier will include a large pool of contingent middle- and low-skill workers without the benefits, income, or security on which a robust and resilient middle class depends.

New policies are needed to provide workers in contingent employment relationships access to benefits, and new institutions are needed to deliver them. There is growing support for the view that benefits should satisfy at least three conditions. They should be portable, attached to individual workers rather than to their employers. They should be universal, applying to all workers and all forms of employment. And they should be pro-rated, linking employer benefit contributions to time worked, jobs completed, or income earned.

Two recent proposals incorporating these conditions call for the creation of “individual security accounts” analogous to US Social Security accounts, but encompassing portable benefits that would be available to all workers, regardless of employment status, and would accrue via pro-rated automatic payroll contributions.

A group of strange bedfellows – “gig” employers, labor organizations, venture capitalists, and bipartisan think tanks – recently issued a letter calling for a stable and flexible safety net based on these conditions. Meanwhile, in Congress, forward-looking policymakers like Senator Mark Warner of Virginia are seeking ways to get ahead of the issues and create momentum for bipartisan solutions.

Much remains to be done before a new safety net for all workers is in place: determining which benefits and protections to include, how to pay for them, and how to deliver them to workers. Labor groups, including unions or new types of labor organizations like and the Freelancers Union, could fill the gap, providing benefits as unions have done in the construction industry and guilds have done in the entertainment industry. In Silicon Valley, where thousands of contractors and freelancers are hired every week, new private companies like MBO Partners are emerging to handle the benefits of contingent workers who work for many employers.

The McKinsey Global Institute estimates that digital labor platforms could increase US GDP by 2.3% and US full-time equivalent employment by 2.7% by 2025. But realizing these economy-wide gains while providing a secure and portable safety net for all workers will require new ways of thinking by companies and policymakers.
