Reading Passage:

The advent of digital technology has completely revolutionized the modern workplace. Gone are the days when an employee's physical presence was strictly required from nine to five. With cloud computing, high-speed internet, and collaborative software, remote work has become not just a possibility, but a standard for many global corporations. This shift has drastically reduced commute times, allowing workers to reclaim hours of their day, which often translates to a better work-life balance. However, this new paradigm is not without its flaws. The blurring of lines between home and office can lead to "always-on" culture, where employees feel pressured to respond to emails at all hours, ultimately leading to burnout and stress.
