Bern Fly Rod Company is a small manufacturer of high- quality graphite fly-fishing rods. It sells its products to fly-fishing shops throughout the United States and Canada. Bern began as a small company with four salespeople, all family members of the owner. Because of the high popularity and recent growth of fly-fishing, Bern now employs a seasonal, nonfamily, sales force of 16. The salespeople travel around the country giving fly- casting demonstrations of their new models to fly-fishing shops. When the fishing season ends in October, the temporary salespeople are laid off until the following spring.
