Once upon a time on a weekday, people got up, got ready, and commuted to a physical work location.
That was the “normal” work routine in many places globally.
On Monday morning, individuals got ready, had breakfast at home/in their commute to work, worked for 8 hours, and then returned home. Same routine for 5 days a week. 2 day weekend and long weekends on certain holidays. Lots of time and money spent on commuting to and from work. How productive this “system/structure” has been is up for debate. Working from home was way less common than it is today.
These days, individuals get up, get ready, and work from their home work station all 5 days of the week or commute few times to their physical work location or still commute 5 days a week. A hybrid work model seems to be here to stay and both employees and employers benefit from this.
