A similar problem was highlighted last week with another firm, Mikey. As is often the case, all is not as it seems.
Mr Ibrahimov is not (or rather was not) employed by UK Mail. He was a self-employed contractor. He entered into a contract where these charges were clearly explained. The company incurs charges when a contractor fails to fulfil their contract in the same way that you would if you employed somebody who did not come up with the goods as agreed. He was presumably happy with the conditions of the contract. It would be interesting to discover if he was genuinely “self-employed”. A recent tribunal appeal lost by Charlie (“Pimiico Plumbers”) Mullins suggested that many firms are using people on a self-employed basis when in fact they do not meet the definition. Whilst Mr Ibrahimov may have a case to take to a tribunal on that basis, he was presumably perfectly happy with the advantages of being self-employed when he signed his contract and cannot complain when clauses in it are not in his favour. I would imagine that he can claim his losses from the driver who ran him over.
