Uber seeks UK chairman as threats to its business mount

LONDON (Reuters) - Taxi hailing app Uber said on Wednesday it had hired a headhunter to fill a new position of UK chairman, as part of a process which began weeks before London’s transport authority stripped it of its licence. The non-executive position would bolster the taxi app just as it fights to retain its licence in the British capital and battles to preserve its business model at an employment tribunal over workers’ rights.
