In this lesson we'll study another crucial particle of Japanese, で. Many confuse it with に. However, after this lesson, you will realize that it is not the same thing. There are times when they overlap, but you'll leave this lesson with the knowledge needed to distinguish them.
1. で and に both frequently translate as "at." With で, however, there is no deep connection implied between the action and the place of said action as there is with に. The best example of this contrast between the two particles can be seen with the concept of "to work."
1. ここで働きます。 VS ここに勤めています。
I work here. I work here.
The first one says that you just work there. You may just be an extra hand, someone that just does things, or the job may just be temporary. The second says that you have been working there; you're employed there. It's the kind of work where you are going to probably be there for a long time. For example, 会社に勤めている.
に relates to the state of something whereas で relates to the occurrence of something. That is why に is used with verbs like ある, いる, and 勤める and で is used verbs like 働く, 会う, etc. However, it is very possible that you will have to use both in the same sentence because of other usages they have.

Don't pass food with chopsticks because this is how bones are handled. Pass food by placing it on a small plate or using the ends. Mismatched chopsticks aren't used. Pointing chopsticks at someone may be considered a threat.
Curve Ball: に働く Exists...
Many students are penalized all the time making the annoying mistake of writing ~に働いています on a test. Unbeknownst to these students, the phrase isn't so incorrect as they have been taught. In fact, ~に働く is pretty common.
Why, then, must teachers distill false information? For one, telling students to google search examples of ~に働いています doesn't result in thousands of instances of "place + に働いています." The word preceding it can be a number of things such as adverbs, time phrases, etc. Furthermore, if a student were to look up 働く in a Japanese dictionary in Japanese, the verb is defined in way indicative of a temporary job position to simply sustain one's livelihood. It doesn't intrinsically imply working in a career sense.
However, when this is all blurred, the state of the job doesn't necessarily matter. After all, native speakers aren't going to consider the state of their job to determine which particle to use.
26. 彼女はうちの店に働いていますわ。
She's working at my store.
