Learn Polish: Czy pracujecie codziennie?

Verbs ending in -ować are special! In the present tense, you have to replace the -ować part with -uj- before adding the person ending. So, pracować becomes the stem pracuj-. Then, because we are talking to a plural "you", we add the ending -ecie to make pracujecie.

Where is the word for "you" in this sentence?

In Polish, you usually drop subject pronouns like wy (you plural) because the verb ending already tells you who is doing the action. The -ecie ending on pracujecie can only mean "you" (plural). Adding wy here would sound unnatural unless you wanted to strongly emphasize it.

Is there an easy way to remember the word codziennie?

Yes, it helps to break it down! In Polish time expressions, co means "every". The second part comes from dzień (day). Put them together and you literally get "everyday" or "daily".

Can I ask this question without using the word czy?

Yes, in casual spoken Polish you can just say Pracujecie codziennie? and make your voice go up at the end, just like in English. However, starting yes/no questions with czy (which acts like "Do" or "Are" here) is the standard, grammatically correct way to ask.
