Back in 1940 a man by the name of John Gallo, an assembly worker at Ford Motor Company, was fired after being "caught in the act of smiling". He had been warned on a previous occasion for "laughing with others". At that time Ford's workers weren't allowed to hum, whistle, or talk with other workers, even during lunch. Henry Ford believed that work was for work and play was for outside of work. He believed the two should never be mixed.
Southwest Airlines has a completely different philosophy. They believe that "people rarely succeed at anything unless they are having fun doing it". If you review their website you see comments like “our people are our single greatest strength and most enduring longterm competitive advantage.”
Part of Southwest Airline's mantra is to:
Don’t take yourself too seriously
Maintain perspective (balance)
Enjoy your work
Be a passionate team player
What is the culture look like at your company? Are the employees excited to come to work or do they dread coming to work? Remember, if you and your team aren't having fun at work you aren't doing your best work.
