No you have to remember that the big 4 need more people in case there is turnover. new hires are also cheaper than existing staff which big 4 partners like. There are a couple caveats though. If the team you support loses their major client then there might be some risk. If there is a huge downturn in the market and revenues for EY, that is also a risk. Generally though, tax and audit are pretty stable. Teams have been losing clients to smaller firms though due to cost pressures. Fall 2023 is pretty close though, so I think you will be fine.
