Learn Hardcore Arabic (Egyptian): كل شهر الموظفة بتبعت الورق للمدير قبل ما نمضي عليه. - Every month the female employee sends the papers to the manager before we sign them.

Putting it first is very natural in Egyptian Arabic when you want to establish when something usually happens. It is similar to English sentences like:

Every month, the employee sends...
Each month, the employee sends...

You could move it later in some contexts, but sentence-initial position is very common.

Why is it الموظفة and not الموظف?

الموظفة is the feminine form, meaning the female employee.
الموظف would mean the male employee.

The ـة ending often marks feminine nouns in Arabic. Because the subject here is feminine, the verb also shows feminine agreement:

الموظفة بتبعت = the female employee sends
الموظف بيبعت = the male employee sends

What does the بـ in بتبعت mean?

In Egyptian Arabic, the prefix بـ on the verb often marks the present/habitual tense.

So:

بتبعت = she sends / she is sending
In this sentence, because of كل شهر, it is understood as a habitual action: she sends

Without بـ, the meaning would change and might sound more like subjunctive or another construction, depending on context.
