WFH, or "Work From Home," describes a professional arrangement where employees perform their duties from their primary residence rather than a corporate office. While originally a perk, it has evolved into a standard operating model for the modern digital economy. WFH requires a high degree of self-discipline and the use of collaborative software like Slack or Trello to maintain visibility. While it eliminates commutes, it necessitates a proactive approach to wellness to avoid the "always-on" trap. Understanding WFH is the first step toward mastering remote lifestyle optimization.
