簡單解釋

網絡的 bandwidth（頻寬）就像一條水管：管子越闊，同一時間可以流過的資料越多。

職場把人也當成這條水管。Do you have the bandwidth? 即是問「你手上還有空間多接一件工作嗎？」；I don't have the bandwidth 就是「我已經滿了，接不下」。

它比 "I'm busy" 客觀，重點是工作量，而不是你願不願意做，所以拿來說不也不失禮。

常見錯誤

✗ I don't have bandwidth to do it.
✓ I don't have the bandwidth to do it.
職場說法通常有 the：have the bandwidth to do sth。
✗ My bandwidth is very busy.
✓ I'm very busy. / I don't have much bandwidth.
bandwidth 是「容量」，不會「忙」；要說容量多或少。
✗ Do you have bandwidths for this?
✓ Do you have the bandwidth for this?
職場意思的 bandwidth 是不可數名詞，不加 s。
✗ I don't have the bandwidth.（對上司說完就停）

只說沒有餘力會顯得推卸；加上原因或其他方案，聽起來更專業。

一個回覆上司加工作的訊息：用 Dictionify 的 Polish 把整段改得自然又專業，刪去的字劃走，新加的字標示出來。

原稿

Hi Peter, sorry I cannot do this new project, I am very full now and too many works. Maybe you find other people.

✨ 改寫後

Hi Peter, ~~sorry I cannot do this new project,~~ thanks for thinking of me. I ~~am very full~~ don't have the bandwidth right now ~~and too many works. Maybe you find other people.~~ because the tender is due on the 30th. I could take it on after that, or Daisy might be free sooner.

I am very full now and too many works → I don't have the bandwidth right now：work 是不可數名詞，不說 works；用 bandwidth 客觀又簡潔。
加上原因 because the tender is due on the 30th，上司就知道你不是推卸。
Maybe you find other people 語氣生硬；I could take it on after that, or Daisy might be free sooner 提出方案，更有建設性。

近義和相反說法

說法	意思	分別
capacity	能力、容量	較正式，常用於人手和產能，例如 "We're at full capacity."
have time for	有時間做	最簡單直接，只講時間，不講精力。
have a lot on my plate	手頭上事情很多	口語，形容已經很忙，常用來婉拒。
stretched thin	分身不暇、資源緊絀	強調人手或精力已經分得太薄。

相反：have time to spare (有多餘時間)、free / available (有空、可以接新工作)

常見問題

用 bandwidth 說「不」，對上司會不會不禮貌？

不會，它反而是職場上較客觀的說法，因為重點是工作量而不是意願。最好加上原因和替代方案，例如 "I don't have the bandwidth until the audit is done, but I can start next Monday."

bandwidth 是可數還是不可數？

職場意思通常是不可數，不說 bandwidths，也不說 a bandwidth。可以說 the bandwidth、some bandwidth、more bandwidth、limited bandwidth。

bandwidth 和 capacity 有甚麼分別？

兩者都可以指工作容量。bandwidth 較口語、多用於個人；capacity 較正式，常用於團隊、工廠或系統，例如 "The factory is running at full capacity."
