If you examine the entire thread - especially my answer at 14:39 - you will find that the question title is incorrect. It is not the Tories who are classifying people who work one hour as "employed". They are classified under a 37 year old international convention.
I doubt anybody working an hour a week would spend two hours travelling to and from it. But, as Gromit says, working less than 16 hours a week does open up a host of benefits not available to those not working at all.
