MINNEAPOLIS— Park Inn and Park Plaza hotels has launched a new business practice, called the “1% Difference,” which encourages each employee to find 100 things throughout their workday that can be done slightly better, rather than focusing 100% of their energy on improving only one item. Tom Griffiths, vp/marketing and sales for Park Hospitality, said this new mindset is accomplished through specialized training, which teaches all employees to recognize situations where a little extra effort makes a world of difference. Some examples of the 1% difference include: hotel front desk staff placing random courtesy calls to guestrooms to make sure everything is satisfactory, hotel maintenance workers sweeping snow off guests cars before they leave in the morning, and general managers arranging for small groups to use their sales office computers after hours to obtain Internet access.
