Serious case of Boomer Mentality - Operations Engineer Bloomberg Employee Review

The place is rampant with folk who have been here for 15 - 30 years. They hoard all the good meaningful work and pass the paper-pushing work to qualified new hires. Feedback about this to TL/Manager? HR falls on deaf years. It's not a revenue-generating group in the company and is heavily neglected in terms of work-life balance. As a new hire, I had multiple people on my team come out a vent their frustrations to me, which tells me they aren't happy and haven't been for a long time. Technology is old at least 8 years behind other fintech/tech companies. Bloomberg as a company doesn't live up to the hype it formerly gathered for its technology and culture.
