I work in a retail store; I tell my customers "Merry Christmas," though not exclusively. I'm merely here to try to point out that to boycott retail stores whose employees don't say "Merry Christmas" to the shoppers is, well... silly. There is NO company policy against saying "Merry Christmas" to customers, and if employees of said stores choose to expound on scripted greetings and farewells to include members of other cultures, it is their prerogative. And if you so choose to boycott these same stores for that reason, that is certainly yours.
What do you expect these stores to do? Disallow employees from saying "Happy Holidays" to customers? Make it company policy for all emplyees to say nothing with the exception of "Merry Christmas?" It is you who is the fascist, if this is your reasoning (ahem, Cobra64).
Doesn't Christianity teach kindness, tolerance, and good morals? What's wrong with opening your heart and including a member of a different culture in your farewell statement (ahem, tolerance)?
I suppose I expect them all to do like Safeway Stores and finally abandon all pretense of celebrating the season in the spirit intended...why shut down just because it's Christmas? I expect them to continue the tacit assault on the majority of American's deep seated cultural beliefs. I expect them to destroy all that remains of our values.
Meanwhile, though not a devoted Christian, I will continue to look for those who believe, "Our mission is to provide...in a manner which enhances the quality of life for our stockholders, employees, customers, associates and suppliers. In so doing, we will deal with integrity and honesty, reflecting that people are more important than dollars and that our purpose is to bring credit to our Lord Jesus Christ."
I don't know which retailer you work for, but the last three that I worked for sent memos to the stores specifying that employees say "Happy Holidays" or "Seasons Greetings." I've been in retail for many years and I noticed this change about 10 years ago. I always thought it was kind of hypocritical since we still put up Christmas trees and other decorations. I've yet to have corporate send a Menorah or anything for Ramadan or Kwanzaa to display.
