Legal Bill - Is this typical ?

Is this typical : Removed the names for confidentiuality purposes but he is Senior Employment attorney ,

While I understand that legal research and review are integral parts of the legal process, I am perplexed as to why a senior employment attorney, who is expected to possess expertise in their field, would require such a substantial amount of time for these tasks. It is my understanding that senior attorneys are typically well-versed in the applicable laws and regulations, and as experts in their respective areas of practice, they should be able to efficiently handle research and review tasks.
