I sympathise - despite being in a cosy 9 -5 office job - because my work tried to pull a fast one last year. They didn't change the "clocking in" clock until we were all in the building - there was a near-riot when we realised what they'd done at lunch time, and were faced with working an extra hour. I mean, do they really think we're that stupid? Actually, it appears that they do. They'll probably try it again on Monday, the "illegitimate children".
