Speaking of editors, would it kill you to use a little brevity? The first ten out of twenty paragraphs of your letter; literally half of it, have little or nothing to do with the "Christmas decorations in stores" topic promised by the title. There's more pointless rambling about the good ole' days than in a Wilford Brimley infomercial about "diabeetus."
Let's hope your bosses at the store are either very inattentive or very forgiving, since you've now taken an internal complaint you had about company policy and published it in the largest newspaper in a relatively small town... with your name on it. In addition to accusing them of being Grinches, you've accused them of naked avarice, hypocrisy, failing to have an adequate number of employees on hand for the holidays, increasing workplace stress, not caring about the customer's or employee's happiness, and not caring about the traditions and values of the country.
If I was your boss(es) and I used my keen detective skills of reading your name after that angry screed, I'd be pretty pissed. You at least had the presence of mind not to name the store, but that hardly changes what you said about your bosses in the open forum of the town's largest newspaper. Nor would it take that much effort for customers to find out what store is being referred to in a town of only 22,000 if they're the type who are given to being upset by this type of thing.
Good luck. I hope it was worth it to make your stand publicly instead of just dealing with things internally at the company.
.But I don't consider that every Christmas lights have a religious meaning. It's also decorated everywhere over here (to a lesser degree than the USA for houses, I think. Silly Americans
