Recently I wrote about reviewing return to work processes and procedures to ensure that they both protect employees and visitors, and comply with legislation.

I mentioned in the article that these return to work processes should address the management of space and the management of people, to limit interactions between people, and minimise risk when any interactions do occur.   

There are a variety of tools and procedures that businesses can implement to lower risks, and many ways in which spaces can be redesigned.  Some of these are more manual and low cost, and others are high tech, and potentially more expensive.   I listed a number of tools and technologies which may assist, which you can see here:

This article from the FT goes in to some of high tech options in more detail.
