Re: Angry note from MIL!!!!!
If the girl works from 7 to 7, then your friend should probably budget some time in on the side to help out, ex weekends or day off in the week, or do some tidying in the evening to keep the home clean - like clear the kitchen at night.
But I have to take some offense here. For one, did the MIL not know her DIL was going to work? Were the expectations of how much housework can be done not laid out in the beginning? Were these things not discussed with the husband prior to marriage?
If she is a woman who is not interested in cooking, that is her right just as much as it's the right of a more domesticated woman to not work. As long as these issues are cleared up before marriage it's fine. There should be no problem.
My daadi had 4 daughter-in-law's and not one of them cooked. I recall she made a statement once about once of them how the DIL's mother had boasted about the girl's cooking but after marriage, turned out she didn't know even how to fry an egg.
No point in lying before marriage.
*When people ask me, I tell them upfront that I can cook some - these are the dishes I can make - this is how I balance my kaam and my household chores. And that this is probably how I'm gonna manage after marriage, and no, I'm not cooking fresh items every day, because I just can't manage with the time. I'm also upfront that I'm generally disorganized at home. *shrugs I don't see the point at all in lying.

So if your friend was upfront about her work schedule and that she might not be able to cook daily, then why would the MIL be talking smack about her?
And furthermore, yes it is very wrong to gossip about your daughter in law. You get respect when you give it.
Always good not to lie in the rishta-process, but also unrealistic to think you are not going to have to make changes after marriage. You will. And so will he. So you never know, you might end up cooking more than you do now.
I agree with everything else you've said. OP's friend needs to offer to help around the house now, but MIL shouldn't be talking behind her DILs back!!
