IC here - performance review question.

I wanted to ask some managers here their take.

I had my performance review, and I'm a 'high' level of a grade below what I achieved last year.

Example, last year I met expectations, this year I am 'nearly' meeting them.

Corporate environment, UK like setting, but not UK (trying to keep it vague, thing we speak English but not UK laws applicable)

I've had feedback about organisation, accuracy of work, attention to detail and a high sickness record, which has contributed to this grade being lower this year. Also not getting my timesheet done on time consistently.

All true, all fair for the overall year. However, since January, I've had 1 sick day, from an illness the whole team had, so, I caught it, at work. Illness prior to this had doctors notes, for things like flu / asthma. And I've been on time with my timesheet since around January too.

Here's the thing, I was diagnosed as partially deaf In November. I am still waiting for hearing aid assessment, been told it could take until August. I told my manager the week after I was diagnosed, I asked for reasonable accommodations in terms of support such as transcripts and meetings being recorded. It was inconsistently done. I asked for written instructions, they don't always happen. Now I know what is wrong with me, I can see that this is a key reason why I'm struggling. Not just the hearing part, but other impacts like mental fatigue from working harder to overcome being unable to hear, tinnitus, sometimes headaches, and honestly, anxiety, now, particularly when the office is loud, that I'm hearing something incorrectly and I'm going to get things wrong.

I had good feedback too, I've passed exams, personal feedback from colleagues is overarchingly positive.

I also had a goal to be promoted, not to management, just from 'x' to 'senior x'. I was originally told a time frame of late 2026/2027... This has been pushed out to 2028. When they asked how I felt, I asked if I could not answer, and process it.

My questions are the following.

Why in the review, did my manager not even acknowledge my newly diagnosed disability?

Why, if I wasn't on a formal attendance plan, was a sickness record (majority with notes from doctors, for diagnosed stuff like asthma) enough to count against me in relation to performance?

What do I do about being explicitly told I'm not meeting x level, but due to being an older employee, I'm being treated like I'm senior x level? Example, at a work event, a colleague asked if I was a manager, I said no I'm x, 'how old are you?' - Because he couldn't understand it.

Whilst my manager was away, I was asked to attend calls another manager had supposed to cover, because I was 'closer to the work' and 'obviously competent'.

Do I mention the above to my manager?

They did try and say that during agreeing ratings there had been a big discussion about if I should be a meets expectations, but the group ultimately decided against it.

I'm scared that this is the start of me being managed out.
