But thankfulness deserves an ingrained place in our managerial cultures. Ed Locke in a classic review of job satisfaction decades ago found that one of most important sources of job satisfaction was simply feedback, especially positive feedback. In the course of our days and weeks, there will be times when we will be glad for the work of others, the contributions of others. In short, we will be thankful for our colleague, our direct report. Let them know. Let them know you appreciate their work, their contribution. It is great to be thankful of another. It is even better to let them know.
