An important job for store managers is to attract customers into their stores through new strategies. They also have sales goals that they must meet each month and can achieve those goals through training, motivating, mentoring, and giving feedback to their staff.
A store manager's goal is to make sure every customer is satisfied with the customer service they received. The saying, "every customer is right," is definitely not a factual statement, but it's a store manager's motto.
All of these responsibilities lead up to something greater. That's right, 45-50 hour work weeks. Someone has to stay late and make sure the store is perfectly ready for the next day. Typically, this won't be a high stress job, unless it's the holidays or a tax-free weekend. Did someone say Black Friday shopping? Good luck!
