Poor pay. I worked at Hannaford from 1996 - 2007. I was promoted 3 times in that span. My salary when I left was $10.35 an hour. That is about one dollar for every year I worked there, and I got exemplary reviews each year. When I left there were cashiers who just started who were making almost as much as I was.
Manager's play favorites. I know it happens everywhere but in the store I worked at it was horrible and I had experience with this for 10 years with multiple direct managers. Sometimes I was the favorite, often I was not but it is almost an encouraged practice at Hannaford.
People who work hard are not rewarded. I worked there for 10 years and was denied several promotion, even ones I was qualified for due to my experience. There is nothing worse than having you boss be fired for incompetency, then having them be re-hired to the same position they were fired from less than a year ago (which I applied for) and then having to TRAIN them to do the job correctly this time. Only to have the stepped sideways because lo and behold, they don't know what they are doing. This happened to me twice in my time at Hannaford as as far as I know my former boss still works there.
This brings me to my next point, Hannaford tends to promote mediocrity. Store Managers do not want to be challenged by department managers so they tend to promote people with just enough ability to do what the department requires. Often this leads to people being promoted beyond their skill level and it is always the hourly associates that have to pick up the slack.
Despite coming in regularly (at least once a week) to over sick-calls or staying late to cover sick calls or help out when the store was short handed I was always yelled at if I was 5 minutes late back from a break or lunch. Even though I knew the job forwards and backwards to the point that at one time every single cashier had been trained by me I was yelled at if I didn't get registers washed or trash emptied because I was myself on register helping customers. Basically in my experience no matter how hard you work you will never be praised only disciplined if you mess up even a little. And the harder you work, the more they expect from you so if ever you cannot meet the level you set for yourself you will be told that you are slacking off and will be disciplined.
