The concept of freelancing and gig work has indeed led to the erosion of worker benefits, primarily because these types of employment arrangements often classify workers as independent contractors rather than employees. This classification allows companies to avoid providing traditional benefits and protections that are typically associated with employee status.

One of the most significant benefits that gig workers often lack is access to employer-sponsored healthcare coverage. In the United States, for example, the Affordable Care Act requires employers with a certain number of employees to offer health insurance. However, many gig workers do not meet the criteria for employee status, and therefore, companies are not obligated to provide healthcare benefits. This leaves gig workers responsible for obtaining their own health insurance, which can be more costly and less comprehensive than employer-sponsored plans.

Retirement benefits are another area where gig workers are often disadvantaged. Traditional employees may have access to employer-sponsored retirement plans, such as 401(k)s, which often come with employer contributions and tax advantages. Gig workers, on the other hand, are responsible for setting up their own retirement savings and do not receive any employer contributions or benefits.

Paid time off is another worker benefit that is often eroded in gig work arrangements. Traditional employees typically receive paid vacation days, sick leave, and other types of leave. Gig workers, however, do not have these benefits and often have to forgo income if they need time off.

Moreover, gig workers often lack access to other protections and benefits such as unemployment insurance, workers' compensation, and protection against discrimination and harassment. These benefits are typically tied to employee status and are not available to independent contractors.

The erosion of worker benefits in gig work has been a subject of concern and debate. Critics argue that the lack of benefits leaves gig workers vulnerable and without proper social safety nets. Proponents, on the other hand, argue that gig work provides flexibility and freedom for individuals to work on their own terms, even if it comes at the expense of certain benefits.
