From Nigel's first link:

British businesses need to up their game and be more productive or risk losing out as the country leaves the European Union, industry bosses have warned. Productivity in the UK grew by 0.9pc and 0.7pc in the final two quarters of 2017, the strongest growth since 2011.

This related to your statement that productivity was 'flatlining', which I think most would understand to mean zero-growth (a flat line on a graph or heartbeat monitor)
"Flatlining" is not a relative term, decided by reference to other member states.

Now we have Chicken Little trying to be Humpty Dumpty. "When I use a word it means what I intend it to mean"
