I can well remember an assembly soon after starting my secondary education, in which the headmaster berated pupils for not having the official school uniform emblem on their blazer (and this was back in the late 60s).
It would take careful examination to see that emblem was not the real deal; in an instant I realised that the school was getting kickbacks from the official school uniform supplier (otherwise why complain about a non-issue).
The FTSE100 company I work for has all sorts of anti-bribery, anti-competitive procedures in place that would not allow the company to behave in this manner. An employee engaged in such a practice would likely be dismissed for gross misconduct.
Why do we allow such behaviour from our schools – which would not be acceptable in business?
