用件するものについて上司に尋ねたい。どちら文章を使ったほうがいいですか？
Hi, I'd like to know how to address to my boss in order to offer help. Are any of the following sentences correct or natural?

Answer

In general saying 上げる should be avoided unless its your friend. I think お手伝いします or 手伝わせてください are more natural . You may say 何か手伝いできる事(が)あれば、是非言ってください。
