The informal sector, characterized by a lack of formal regulation, social security, and employment benefits, has always presented unique challenges for its working class. However, in recent decades, the nature of these problems has evolved significantly, driven by globalization, technological advancements, and changing economic policies.

Traditional Problems (Persistent but Evolving): Historically, workers in the informal sector have grappled with low wages, long working hours, hazardous working conditions, and a complete absence of job security or social protection (like health insurance, pensions, or paid leave). Exploitation by employers, middlemen, and even local authorities has been a constant threat. Lack of collective bargaining power due to fragmented workforces and legal restrictions on unionization further compounded their vulnerability. These issues remain prevalent, but their manifestations are changing.

Emerging and Intensified Problems:

1. Casualization and Gig Economy: The rise of the gig economy, facilitated by digital platforms, has introduced new forms of informal work. While offering flexibility, it often comes with intense pressure, performance-based pay, and a lack of employee status, denying workers basic labor rights and benefits. Traditional casual labor has also intensified, with more workers engaged in short-term, precarious employment without any formal contracts.

2. Increased Competition and Wage Stagnation: Globalization and liberalization have led to increased competition, both from formal sector industries and within the informal sector itself. This often results in downward pressure on wages, making it harder for informal workers to earn a living wage, especially in sectors like street vending, construction, and domestic work.

3. Technological Disruption: While technology creates new informal jobs (e.g., delivery services), it also threatens existing ones through automation or by making certain skills obsolete. Workers in traditional informal trades may find their livelihoods impacted, requiring them to adapt or face unemployment.

4. Urbanization and Migration Pressures: Rapid urbanization and rural-to-urban migration swell the ranks of the informal workforce, particularly in cities. This influx intensifies competition for limited informal jobs and resources, often leading to overcrowded living conditions and increased vulnerability for migrant workers who lack social networks and support systems.

5. Lack of Policy Recognition and Social Protection: Despite the informal sector's significant contribution to the economy, it often remains largely invisible in policy frameworks. Governments struggle to regulate it effectively or extend social security benefits, leaving a vast segment of the working population unprotected. The COVID-19 pandemic starkly highlighted this vulnerability, as informal workers were among the hardest hit, lacking safety nets.

6. Environmental and Health Hazards: Many informal sector jobs, such as waste picking, construction, and small-scale manufacturing, expose workers to severe environmental and health hazards without adequate safety equipment or regulations. Climate change also disproportionately affects informal workers, especially those dependent on natural resources or outdoor work.

In essence, while the core issues of precarity and exploitation persist, the informal sector's working class now faces a more complex landscape shaped by digital platforms, intensified competition, and a continued struggle for recognition and social justice in an increasingly globalized and technologically driven economy.
