也许你一直在“谋划”愚人节这天搞个什么恶作剧来戏弄同事一把，但在行动之前，你应该知道你的同事很可能并不喜欢这样的做法。

An image of an office prank. Pranks are unsuitable for the office, according to a recent survey.

In a recent survey by The Creative Group, 58% of advertising³ and marketing⁴ executives said pranks（恶作剧） are unsuitable for the office, 33% said it was somewhat（多少，稍微） appropriate and only 4% said it was very appropriate.

"With many creative teams challenged with high workloads⁵（工作量） , office pranks may be viewed more as a distraction⁶ than an amusement," said Lara Dodo, vice-president of The Creative Group's Canadian operations.

Dodo says pranks can also potentially alienate⁷（疏远，离间） or hurt someone's feelings if not carried out in good taste.

Researchers talked to 200 marketing executives, 100 employees and 50 advertising executives in a telephone survey.

But just because an April Fool's prank might be frowned upon（不悦，皱眉） , it doesn't mean you can't joke around while at work.

"Well-intentioned humour when shared amongst teams can create a positive work environment, especially when business is demanding. Some light-hearted wit（智力，才智） can increase morale⁸（士气，斗志） and motivation, resulting in improved productivity and retention⁹（记忆力，滞留） ," Dodo said.
