Just a "workers on boards" nugget, but Capita has announced it is seeking to recruit two employee directors. You can read the press blurb here or the story in the Times here.
When I dug around a bit I discovered that this had actually been announced back at the start of August in the H1 results:
So that's three companies so far that I know that will have worker directors next year (First Group, Mears Group and Capita). This will obviously go higher. I reckon in a few years it could be quite commonplace.
