Productive WFH workspaces can also differ by the computing device the remote worker uses. For instance, a remote worker in a design position will likely benefit from a different setup than the likes of a data analyst or accountant. Not every home office will follow the same blueprint. To stay productive, dedicate a workspace and build it out with the same amenities - ample desk space, a big computer monitor, and ergonomic solutions - that you enjoy in the office.
If at all practical, you should set up a home office when working from home (WFH), especially if you will be WFH for the long term.
