Is this a common management dynamic? Boss taking credit and visibility while I do all the work

Hi all! I’ve been dealing with a situation at work recently and would love some of your opinions.

I’ve been consulting with Claude, which I’ve used to help summarize the situation below, but I know how AI can make it seem like everything a user says is justified and a great idea, so would love some feedback from actual people.

Here it is:

I’m a senior individual contributor at a large corporation, and I’m trying to understand if my situation is typical or if I should be more concerned.

Background: I’ve been in this function for 3 years, reporting to a manager who originally oversaw just our function. Shortly after I joined, she went on extended leave and I essentially ran everything autonomously. When she returned, the company expanded her scope to include a second function, and she’s focused primarily on that new area while I continued managing our original function. I was promoted in title, overseeing the same function about 1.5 years ago.

The pattern I’m seeing:

• I handle all strategic planning, stakeholder management, and execution for our function
• She communicates my work externally, often needing me to draft or heavily edit her communications for accuracy
• When I’ve been overcapacity and she’s had to step in, tasks either don’t get done or are done incorrectly and I end up fixing them anyway
• She told me for months I’d be getting a direct report to help with workload, only to later say “I don’t know what happened, but it’s too late to change” - that person now reports to her instead
• On my 2024 year-end performance review, I was told I have “visibility challenges” and people don’t know what I work on, yet she continues to be the one communicating out my work
• Direct communication between me and senior leadership has been redirected to flow through her. If senior leadership does reach out directly, after I respond, my boss follows-up with some message like, “that’s right” to show they’re involved and/or we’re aligned, even though they wouldn’t have been able to answer on their own

Recent developments:

• During our busy season, I worked 60-70 hour weeks delivering everything on time while she maintained normal hours and took significant time off on key deadlines
• She sent the success communications to senior leadership after I wrote/corrected them
• Right after this successful period, my scope is being split and given to the new hire who was supposed to report to me
• I’m getting more frustrated and pushing back on requests, which is probably becoming apparent

Questions:

• Is this level of “communication management” normal?
• Should managers understand the details of their direct reports’ work, or is it okay for them to just handle communications?
• How common is it for individual contributors to essentially run entire functions while managers focus elsewhere?
• Am I overreacting to what might be normal corporate dynamics, or is this dysfunctional?

I’m actively job searching now, but curious if this is something I should expect elsewhere or if this particular situation is problematic. My boss is aware of this and said they’d provide me a referral, so I’m also debating on if it’s even worth raising any of this stuff at this point or not. Mid-years are upcoming, and I’ve been asked to provide feedback on my boss to their boss.
