MPs seek to ban labourers working in hot summers?

Tabled by lefty John McDonnell, signed by many across the parties including Peter Bottomley (who signs anything and everything) I give you the following idiotic EDM.

That this House notes that whilst there is a legal minimum workplace indoor temperature, there is no clear legal maximum workplace temperature so that conditions can vary greatly from employer to employer; further notes the many employees, particularly those working in bakeries, are often subjected to very high temperatures which can impact seriously on their health and well-being with effects ranging from discomfort, stress, irritability and headaches, to extra strain on the heart and lungs, dizziness and fainting and heat cramps due to loss of water and salt; and urges the Government to provide clear and coherent guidelines to employers about how to combat heat in the workplace, and to introduce a maximum working workplace temperature of 30C (86F) and of 27C (81F) for those doing strenuous work.

That's gardenrs in a hot summer screwed. Professional tennis players (who are at work of course) banned from playing at Wimbledon if the temperature rises. Lord knows what it will mean for the 2018 World Cup bid if June in that year is a bit on the hot side - global warming after all.

Oh and if you're a labourer it doesn't even have to be that warm before you'll be told to lay down your tools.

P.S. The failed Labour leadership candidate McDonnell (and yes, Bottomley too) is also calling for price control to return. No doubt because it was such a roaring success in the 50s, 60s and 70s.
