Since OP is a new poster, we obviously don’t know much about her. We can only go off of the 11 posts she’s made on this thread which are the total of her CC posting history.
Here’s some bits that struck me:
"But you already probably knew that these relatives have no manners.
That’s fair to conclude. But I suppose we figured the magnitude of this award — a free $10,000 certainly far exceeds any previous gesture — would elevate their etiquette, at least slightly."
“By the way, it was won several months ago. We’ve been biting our tongue for months thinking we’d get a thank you at the open house. Or maybe around move-in time”
“For lack of a better word, it’s trashy and I’m honestly disgusted with them. I also know if the $10,000 was out of their checking account they probably wouldn’t have a new leased car in their garage. I should also say this isn’t the first time they’ve acted a bit uncouth, but the $10,000 would top any previous gestures by a large margin.”
MY THOUGHTS:
Since there is no mention of brother or sister by the OP, just mention of a niece and “her parents”, I’m guessing this is her husband’s sibling. OP can correct me if I’m wrong but if true, her husband should deal with it.
There is obviously family history here which taints the reaction.
Since you point out at least twice that you weren’t surprised given their past behavior, why have you waited months? As soon as you were made aware that niece received the scholarship, you should have point blank stated to niece and her parents that a letter of appreciation to your and your husband’s employer should be sent out right away. Instead you said nothing. Why would you sit on that for months? Did you not think that acknowledgement to your employer to be important enough?
However, this thread obviously wasn’t about your company receiving thanks (you know, the entity that actually gave the $10K?!), it was all about you getting what you deemed to be proper thanks. Of your 11 posts on the subject, it wasn’t until your 6th post that you chose to bring up that tidbit about the employer receiving no acknowledgement of gratitude, which actually to me is the most egregious faux pas, which I find telling.
Yes, they all most definitely should have thanked you but to me that isn’t cause for you to reciprocate with your own bad acting. As the old adage says, “Two wrongs don’t make a right”.
There is room here to do two things - fix the situation and be the bigger person. Contact your niece ASAP and explain that you’ve found out your company didn’t receive a thank you letter. If this is your husband’s family, then he should be the one doing it. Explain that every other scholarship recipient did. Explain why it is important that she do so now ASAP - future money to be applied for over the next 3 years that she risks consideration for (include info on reapplying) and also that it reflects badly on you and your spouse as employees. Word it so that you don’t think they are being intentionally rude and that you are just trying to help them out by helping them understand how the process works. Do it by email and cc the parents. I’m sure folks here can help with wording if you feel stuck finding the right words and a non-judgmental tone. This is salvageable. After that point, you can reassure yourself you’ve made an honest attempt to take the high road. If they take it poorly, then that’s on them. If they rise to the occasion and amend things after receiving your email, forgive and move on.
p.s. The leased car is beside the point and irrelevant to the discussion IMO.
