Writer of Publix #1150 is obviously just a disgruntled employee. I have shopped at Publix for many years and I worked for them for 10 years.
Publix spends a lot of time and money to ensure cleanliness and quality. I have seen managers fired for less than that person's article claims. Sexual harassment is never taken lightly. If it was reported, trust me, there was a full investigation in to the matter.
As far as bad produce or milk, maybe a mistake every now and then, but definitely not the norm, and I can assure you their quality far exceeds any other grocery store chain in the U.S. I can tell you from personal experience, Publix works hard at striving for perfection, but as we all know... Nothing is exactly perfect...
If you want the closest thing to it in this business, shop at Publix, the extra 10 or 20 cents you spend is definitely worth it.
