I discovered the value of the teabag from the leader of a plant hire business in the UK. When she was appointed the staff were dismayed. Plant hire is a boys club where they all get to play with Bob the Builder type of equipment. Why on earth was a girl running a boy's club? She was not 100 percent welcome.
Even the leader was not quite sure what to do with her new role. She was more familiar with office plants than with excavators and drillers.
So she set about what she did best: drinking tea with the staff. She went to each plant hire location, sat down with the staff and drank tea. And she listened to what she could do to help them. Often it was little things: have a safe place to lock up their personal tools at night; have a new Union flag for the flag pole; new clean uniforms to give the right image. There were also more substantive changes which they wanted: more autonomy on buying plant to hire out, and more autonomy on setting prices, which went alongside giving them more responsibility for overall profit performance.
She listened and she made the changes. Most of the changes were very low cost. The more substantial ones gave each plant hire location more responsibility.
The result was that performance leapt forwards. Just as important, the leader became hugely respected by all the staff. They had rediscovered their pride in working in a Bob the Builder sort of business. And they had at last found a leader understood that communication does not just mean talking longer and louder: it means listening well and responding with deeds not words.
I asked her what the secret of her success was. "Always carry a box of teabags with you" was her reply. Tea may be the secret of management success.
