OP, no one here thinks you are paranoid. it's understandable that you feel frustrated. You've had a tough reception but I want to try and separate out a few things.
- The Karen pushback
I think your treatment on the thread has been unfair on this. You clearly made the Karen comment, not to defend use of the word, but to explain how you've been treated. A lot of people on mumsnet love to jump on things and it's clear people just jumped on you about that issue in a way that made no sense.
- Your posts are extremely confusing
Completely separately to the Karen comment, a lot of posts stated that this was a word salad or that they couldn't understand what you were saying. I think you read this as them ridiculing the concept of you being dismissed or undervalued but to me they are being literal. Your posts are extremely confusing!! Remember we don't know you or the situation and only have what you are saying. Your first post was about age discrimination. Then it became about being a specialist. Then management love you. Then they hate you.
Even the pie / curry analogy is unhelpful because whilst it tells us that you are a specialist in one area it doesn't actually shed any light on company/industry culture that would allow us to give advice. How senior are the people involved? How senior are you? How important are the various "pies" or "currys" to the bottom line of the business? If you just said you were a consultant etc, people could give better advice.
Like "I have written multi-paragraph letters of complaint and requested to see the manager"
What manager?
Your manager? Their manager? The CEO? The board? What is the management structure here? You want advice about to better manage your organizational relationships but it's really hard to understand what is going on.
Poeple have asked follow up questions that you'e ignored, such as
@SuzieCarmichael asked
- who is your line manager and were they involved in recruiting you / the decision to add your specialism to the company’s range of services?
- have you clearly expressed your concerns to your line manager with constructive practical suggestions for how things could be changed to improve the service quality for clients?
- do you have a good relationship with anyone else at a senior level who you might be able to discuss this with? Have you discussed it with them?
These is the kind of information that would enable people to give decent answers. Instead you keep replying back semi sarcastically but vaguely!
Please please please don't take this as a criticism. I'm not trying to insult you just point out where I think there's a disconnect. If you could just give clear answers to some basic questions in a paragraph format, then I think people would be able to refocus on fixing your problem.
