An employment tribunal ruling could extend generous British employment laws to thousands of employees under foreign contracts who work in the UK for only a small part of their time. The tribunal ruled that four United Airlines flight attendants who spent only 5% of their time in Britain were entitled to the protection of British law. This may extend to other industries and the ruling - if upheld - may also benefit employees based in Britain who often work abroad.
