Ahhh, I see. I think she doesn't feel heard. Sometimes when some women complain, they aren't looking for solutions so much as they want to someone to talk to them and let them comment on their issues. In the end it's all about feelings.
When she complains about her job, provide less in the way of solutions (as crazy as that sounds), and instead dig more into why the issues bother her. If she really is vexed by her job, then I'd wonder:
What does she want to do about the issue with her job? How does she feel about it (does she dread going to work)? How does she feel about the solutions offered to her? How does she expect it to realistically resolve? What is stopping her from taking all the advice gives to her?
I wouldn't be direct with these questions but it is something good to know to figure out where her head is at, if that is the issue.
Ultimately she probably doesn't feel heard and by extension, appreciated (women have a tendency to equate one thing for another, even when they aren't really related). Helping her to feel heard or appreciated is a step in the right direction.
