Like many who spoke for this article, Shane Garcia, the former Chicago manager, talked about Apple with a bittersweet mix of admiration and sadness. When he joined the company in 2007, he considered it a place, as he said, that “wanted you to be the best you could be in life, not just in sales.” Three years later, his work life seemed tense and thankless. He had little expectation that upper management would praise or even notice his efforts. In recent years, the level of unhappiness at some stores was captured by an employee satisfaction survey known in the company as NetPromoter for Our People. It’s a variation of a questionnaire that Apple has long given to customers, and the key question asks employees to rate, on a scale of one to 10, “How likely are you to recommend working at your Apple Retail Store to an interested friend or family member?” Anyone who offers a nine or 10 is considered a “promoter.” Anyone who offers a seven or below is considered a “detractor.” Kevin Timmer said the internal survey results last year at the Grand Rapids store were loaded with fives and sixes.
