Crowds on demand, also known as on-demand labor or the gig economy, refers to a workforce model where individuals are hired on a short-term, project-based, or freelance basis through online platforms. These platforms connect businesses or individuals with a pool of independent workers who can provide services ranging from simple tasks like data entry and transcription to more complex skills like software development and graphic design. This model offers flexibility and cost-effectiveness for employers, while providing workers with opportunities to earn income and control their work schedules. However, it also raises concerns about job security, benefits, and fair labor practices.
