(Although strictly a personal tax liability, BA chooses to pick up the tax bill on behalf of both employees and pensioners and settles this with Her Majesty's Revenue and Customs every year.")
Does BA do this at the employee's marginal rate of income tax or on a pre arranged basis with the revenue authority or if not on those basis, then on what agreement do they have. There has to be a difference between travel on BA incurred about as a positioning to work and travel solely for recreation on the part of the employee or the employee's nominated proxy. Is the benefit cumulative and even large enough take the value of a salary in to the 40% tax bracket.
So WW plays a clever waiting game while the conference is on, presumably making the hope that the union themselves will throw BASSA out. At the same time, if he does not give way on the travel perks, he must save BA a fortune in tax money. There's a bit of the pension fund problems still to come?
