1._____
It is often said that politeness costs nothing. In fact, frequently hearing the phrase "thank you" or "well
done" means the same to staff as a pay rise, researchers say. Praise and encouragement makes employees
more likely to work hard and stay in their jobs, saving on the cost of finding replacements.
2._____
A third of 1 000 workers surveyed (调查) by consulting firm White Water Strategies (WWS) said they
did not get thanked at all when they did well, and a further third said they were not thanked enough. In both
cases, staff said they felt undervalued, meaning they were less likely to exert (使努力) themselves and were
more likely to look for employment elsewhere.
3._____
The yearly result is around 5.2 billion in lost productivity from employees who would improve their
performance if they felt more appreciated, WWS claimed. According to the company, praising staff has
the same encouragement as a l percent pay rise, and works out much cheaper for bosses.
4._____
Three out of four employees said that regular appreciation by their bosses was important to them, but
only a quarter said they were actually given as much praise as they felt they needed. The survey found that
those in blue-collar and manual (体力的) jobs were less likely to be given any recognition for doing well.
5._____
In regional terms, Scottish staff felt most undervalued. Four out of ten workers said they were never
thanked and eight out of ten said they would like more praise. However, workers in the Northeast are less
impressed by being praised by the boss, for only 69 per cent said they felt the need to be told "well done"
regularly. Older employees and women need the most reassurance, according to psychologist Averil Leimon,
a director of WWS. She said that words of praise did more than create a pleasant place to work-they could
even increase profits.
