Writing in the company bog, Salesforce declares the  "9-to-5 workday is dead" and that it will allow employees to choose one of three categories that dictate how often, if ever, they return to the office once it's safe to do so.

Salesforce will give employees more freedom to choose what their daily schedules look like. The company joins other tech firms like Facebook and Microsoft that have announced permanent work-from-home policies in response to the coronavirus pandemic.

Salesforce's chief people officer Brent Hyder said: "As we enter a new year, we must continue to go forward with agility, creativity, and a beginner's mind -- and that includes how we cultivate our culture. An immersive workspace is no longer limited to a desk in our Towers; the 9-to-5 workday is dead; and the employee experience is about more than ping-pong tables and snacks. In our always-on, always-connected world, it no longer makes sense to expect employees to work an eight-hour shift and do their jobs successfully."

He said: "Whether you have a global team to manage across time zones, a project-based role that is busier or slower depending on the season, or simply have to balance personal and professional obligations throughout the day, workers need flexibility to be successful."
