LAST month, America’s National Law Journal told its readers that "employment lawyers are warning lovestruck co-workers to take precautions in the office before locking lips outside". The advice came too late for Harry Stonecipher. The boss of Boeing was forced to resign last weekend—for reasons that will strike many outsiders as absurd—after his board were told of an affair that the 68-year-old married man had been conducting with a female employee "who did not report directly to him".

Inevitably, as the week rolled on, details of the affair rolled out. The other party was reported to be Debra Peabody, who is unmarried and has worked for Boeing for 25 years. The couple were said to have first got together at Boeing’s annual retreat at Palm Desert, California in January. After that much of the affair must have been conducted from a distance: Mr. Stonecipher’s office is at Boeing’s headquarters in Chicago; Ms Peabody runs the firm’s government-relations office in Washington, DC. They exchanged e-mails, it seems, as office lovers tend to do these days, and therein probably lay Mr Stonecipher’s downfall.

Lewis Platt, Boeing’s chairman, said that Mr Stonecipher broke a company rule that says: "Employees will not engage in conduct or activity that may raise questions as to the company’s honesty, impartiality, reputation or otherwise cause embarrassment to the company." Having an affair with a fellow employee is not, of itself, against company rules; causing embarrassment to Boeing is. It seems that the board judged that the contents of the lovers’ e-mails would have been bad for Boeing had they been made public. Gone are the days when a board considered such matters none of its business, as Citibank’s did in 1991 when its boss, John Reed, became the talk of Wall Street for having an affair with a stewardess on Citi’s corporate jet.

At Boeing, a whistleblower is said to have forwarded the messages to Mr Platt. In general, e-mails are encrypted and not accessible to anyone who does not know the sender’s password. But many firms install software designed to search electronic communications for key words such as, "sex" and "CEO". A study last year of 840 American firms by the American Management Association found that 60% of them check external e-mails (incoming and outgoing), while 27% scrutinize internal messages between employees. Sweet nothings whispered by the water cooler may travel less far these days than electronic billets doux.

Boeing is particularly sensitive to embarrassment at the moment. Mr. Stonecipher was recalled from retirement only 15 months ago, after the company’s previous boss, Phil Condit, and its chief financial officer, Michael Sears, had left in the wake of a scandal involving an illegal job offer to a Pentagon official.

Mr Stonecipher, a crusty former number two at Boeing, was brought back specifically to raise the company’s ethical standards and to help it be seen in its main (and affectedly puritanical) market, in Washington, DC, as squeaky clean. Verbally explicit extra-marital affairs are inconsistent with such a strategy, it seems, though they are not yet enough to bring down future kings of England.

In corporate life, such affairs are hardly unusual. One survey found that one-quarter of all long-term relationships start at work; another found that over 40% of executives say they have been involved in an affair with a colleague, and that in half of these cases one or other party was married at the time. Many a boss has married his assistant and lived happily ever after. Boeing apparently used to accept this: Mr. Condit’s fourth wife was a colleague before they married.

It can be inferred from the text that（）

A. company love affairs often lead to a much happier marriage

B. it is fairly popular for bosses to have affairs with employees

C. the future kings of England will not be involved in any affairs

D. Boeing has adjusted its strategy in terms of corporate affairs
