Is the `是` always used along with the `的`?

not necessary. In fact 是 is used with a noun or a noun-like phase.

verb (verb phase) + 的 is like a noun, but may have different meaning. for example:

吃 (verb, eat) 的: something that could be eaten

喝水 (verb phase, drink water) 的: somebody who is drinking water / drank water

<p>These other answers are good, but they're missing the crucial element, which is <em>why</em> you have the <code>的</code> in that sentence. It's because <code>是</code>, roughly translated into English as <code>is, am, are</code>, is a linking verb that is expecting a noun. If you said <code>我是九点去上班</code> that would essentially mean, <code>I am go to work at nine.</code> Which, of course, doesn't make sense.</p>

<p>However, <code>的</code> takes whatever is before it and turns it into an adjective, thus making "go to work at nine" an adjective. You're probably thinking, "Where's the noun, then?" Well, the noun is implied. That means that <code>我是九点去上班的</code> translates into <code>I am a go-to-work-at-nine-type of (implied noun)</code>, or rather, <code>I am a person who goes to work at nine</code>.</p>

No, that explanation is wrong. Here 的 just simply makes the sentence into "past tense". It's more like explaining a one-off event (I went to work at nine today).

Another example:

A: 你今天怎么没做饭啊？(Why didn't you cook today?)
B: 哦，我是在外面吃的。(Oh, I ate outside.)

@EdwardFox, I'm not sure I agree with you there. It doesn't necessarily imply past tense. 他是吃素的 can translate into "He's a vegetarian", implied "that is the current state of his eating habits".

@LarsAndren Yes, you're totally right in your context, which falls into the category of "a do-something-type-of (implied noun)" perfectly. But I can also give many examples that the same sentence structure represents one-off event in past tense.

今天我是在学校就把作业做完了的。(past tense)
她是已经有工作的。(do-something-type of)
昨天他是在健身房洗澡的。(past tense)
你是经常失眠的么？(do-something-type of)

Context matters.

The "...-type" can be right, but still `是……的` can represent an emphasize of past truth. Plus, there is `去` which is rarely used in that "type" case. 

-妻子：你什么时候出门的？(Wife: When did you get out of the house?)
-丈夫：我是九点去上班的。(Husband: It was nine when I was going to work.)

-领班：你是哪个班次的？(Head: Which shift are you on?)
-工人：我是九点上班的。(Worker: I am on the nine-o-clock shift.)

@EdwardFox, right, I thought you meant that it was always implying past tense. However, my native speaking (Hunan & Taiwan) contacts didn't feel the past tense meaning in the original sentence 我是九点去上班的. They agreed on the "type" case though. Guessing this could be one of those tricky ones that depends on which person you ask.

@EdwardFox The problem with the "Context matters" argument is that tense in Chinese, no matter the grammar pattern, always depends on context. So while `今天我是在学校就把作业做完了的` does imply past tense in that context, so could `今天我在学校就把作业做完了`.

In the reply to `你是什么时候去上班的?`, what does the `的` in `我是九点去上班的` mean? I think that without the `的`, the sentence makes sense in and of itself, right?

And the meaning is that `I start to work at 9:00 am.`..., right?

These other answers are good, but they're missing the crucial element, which is *why* you have the `的` in that sentence. It's because `是`, roughly translated into English as `is, am, are`, is a linking verb that is expecting a noun. If you said `我是九点去上班` that would essentially mean, `I am go to work at nine.` Which, of course, doesn't make sense.

However, `的` takes whatever is before it and turns it into an adjective, thus making "go to work at nine" an adjective. You're probably thinking, "Where's the noun, then?" Well, the noun is implied. That means that `我是九点去上班的` translates into `I am a go-to-work-at-nine-type of (implied noun)`, or rather, `I am a person who goes to work at nine`.

Make sense? It sounds a little convoluted, but that's what's going on.

Here it's a 是 + 的 combo sandwich, where 是 + 的 emphasizes what's in the middle.

`我是九点去上班` doesn't *sound* right - because here 是 and 的 are like bookends with one bookend missing.

You could however just say `我九点去上班` which would sound absolutely fine.
