So allow me to translate as a former INFJ "boss" type:
1. Emotional expressions. It annoyed me to no end that my boss had a seemingly infinite number of facial expressions but there was no real discernible way to interpret what they meant. There would be moments when I would try to explain something to her and she would just stare at me with facial expression that was just completely unreadable. It also annoyed me that she could change her emotional expression so rapidly, as if she was living from feeling to feeling.
They are used to give people a subtle hint that something isn't quite right. The other options are a) butting in and not letting them complete a thought or b) offering a cold hearted critique that's likely to create hostility in some people at the end.
2. Passive aggressive behavior. Another thing that drove me nuts was that my supervisor would never mention when we weren't doing things the way she wanted, apparently to avoid conflict with us, and then she would explode on one of us and make a big show of it in front of all the others and leave use feeling like crap for the whole day.
Would probably follow those emotional expressions if people weren't intuitive enough to pick up on and translate them. INFJ's are like... well... parrots. We give a whole lot of clues and hints as to how things are going and what we're thinking, but they aren't always vocalized. The resulting outburst is the accumulation of every prior failed attempted to get our points across subtly.
3. Intolerance of task oriented people. I'm a task oriented individual and as long as you tell me what to do and the steps to do it, then I'm happy to get it done. But no, this supervisor seemed to have a great dislike of us task oriented workers and she would only tell us a couple steps and then tell us to ask her questions if we ran into any problems. Of course that often meant when she wasn't available we had to make assumptions, which often made her very angry, especially if they were wrong. But as per assertion 2, we wouldn't hear about it until later.
I have to keep myself in check when I deal with these people as well. Even though your profile says INTP, I'm wondering what percent of that Ni is really Si? Most of my trouble comes from those types and they are almost always task oriented individuals as well (especially if you combine the ST traits).
The knee-jerk reaction of what I see, and probably hers too, are people who are incapable of competent, independent thoughts. I like giving people a job and letting them do it; "Get from A to Z and don't tell me how you did it, just do it." kind of mentality. People sitting there needing things laid out in a structured, orderly plan, tend to drive me insane, especially at work... where results are almost always all that ever matters.
Think of it in terms of her boss (if she has one). He/she/they probably look to her to get a result. "Sell x widgets by the end of the month". She then needs to show her boss that she sold x widgets by the end of the month. Odds are, her bosses could care less about how she goes about selling them as long as she stays within company policy.
Now people in her department come along and need things explained to and laid out for them. That's a huge monkey wrench being thrown in to the gears. Instead of working like a well-oiled machine, she now has to stop what she's doing, lose that time and productivity to explain things to her staff. All the while, her boss wants the results from her regardless of her staff's "quirks".
The further down the line you get form the upper managers, the more pressure is being put on the mid-lower managers and the less tolerance you'll probably get from a boss if you need things laid out or explained for you. You can get away with being that type of person in the higher levels than you can at the lower levels; at that point you can write the policies and the SOP's as you go.
4. Revisionist. I was astonished to see that my supervisor actually remembered things differently than everyone else. If she made a mistake, then after the fact, she would remember a different accounting of what happened than everyone else, in which she was not responsible for the mistake.
This isn't an INFJ trait. I've had a very ENFP boss who did that non-stop. It's a human trait, not really an MBTI one that can be locked down to one type only.
5. Excessive care to detail. This supervisor created rules like "no incomplete sentences on paperwork" which continues to blow my mind since they were beyond and above what was necessary and added tedium to the work.
Welcome to the world of "J's". As a "P" it's going to be rough! We like things tidied up after they're used, forms that are evenly spaced, formatting that's easy to read, grammar that follows the rules and communications that form complete thoughts. I even annoy myself when I write a letter and I start two lines with the same exact word!
You need to realize that your boss is going to be like this while your boss needs to realize that not everyone is going to be like her. Neither of you are going to change overnight.
Also... don't be afraid to use that intuition to "read between the lines" and make some independent thoughts and judgements. I know I"d much rather get a project handed to me with some errors but minimal interruptions rather than being interrupted every day or every hour and still have errors (face it, we tend to be perfectionists a lot of times so we'll almost always find an error!).
And lastly... follow through and finish everything to completion. Dot your I's, cross your T's. If you need to, cut your goals in half or take twice the time you need so that you can thoroughly finish them. Say, if a project would take you 4 hours, try to extend it to 5 hours and use that extra hour to go over it with a fine toothed comb. I've seen it happen with a whole lot of "P" types that they bite off a whole lore more than they can chew and tend to get overwhelmed. The scariest parts are when they don't realize they're overwhelmed and they just act on instinct and habit as though it's a normal state to be like that. That's something that a lot of the "judging" personalities are probably going to pick up on rather quickly.
For her....
Actually tell her these things, outright. INFJ's will sit there in our endless NF loops, wondering, hoping, thinking, praying that things we hear, say and do will go over with others. Without direct, blunt feedback, it's easy for us to get lost.
So tell her things like (but not word for word, obviously) "You want it done right, or you want it done fast?" if she makes a big deal about a project or something along those lines. Just giver her something to make he realize reality doesn't always match the ideals in her head. But don't rub her face in it or make it personal... that's something you'll never recover from!
If you need to, also sit down with her and just express some of these things. You'll probably get a lot of facial expressions and looks, but probably won't get a very immediate reaction. We need thigns to sink in for a while and look at the different perspectives before we commit to a thought.
