Time magazine examines the mindsets of employers using independent contractors and reviews a study that found more than 80% of companies that use independent contractors say that they do so because they can quickly adjust the size of their workforce, save money and tailor the worker to a specific task. However, more than half of the firms polled also reported independent contractors are not as invested or loyal as employees, and that they’re not always around when needed. Nearly half say they’re harder to retain.
