Does it matter?
According to a Yougov survey, over 1/3 of us Brits think our jobs make no contribution:

Hard to justify overtime to yourself if the job is pointless. So I wonder whether any of the people in the sample thought that.
Of course that survey was published in 2015, so maybe things have got better since then.
