I think (and I'll use myself as an example) as an INFP who's taken a fairly mundane path as a lab tech, one of the biggest issue I have is reconciling what I think is right and proper work place conduct with what actually happens in the work place. I have a really polarising effect, and I am fairly uncomprimising in that aspect. It caused me alot of pain and unhappiness though, although it goes without saying I'm almost always the union representative eventually, but there are times when I wish I could keep my head down, and let some else cop the flak for once.
Although one place I left, said they missed how much I made every one feel vauled, and how much I laughed (I have a pretty distinctive and infectious laugh apparently). They didn't know how much I added until I was gone. It was very sweet they told me.
At the time I left though, I had gotten exhausted and burnout constantly trying to bring managment's attention to the excessive work load of every one on evening shift, and the constant pressure put on a few individual's shoulders, because they were the only one's truly capable of handling night shift. (I noticed after I left, they had to hire two people in my place.) I wasn't feeling very valued at the time.
I do think people out there don't always know what makes us feel warm and fuzzy. Grandiose gestures don't work for me, they just make me feel obligated, but some thing like grabbing me a coffee on the way to work knowing I'll be dying for one cause I've already been at work for two hours, let's me know you've really thought of me. Or getting lunch for me, because you all my perferences will be gone by the time I finish up the lunch time round of work. It's really small gestures like that, that let me I'm appreciated.
