Dear teacher,

please, check my grammar in this sentence:

//The letter was posted a week ago and it had arrived to my work yesterday before I went home.//

There is the order of events in which they happened:
1) The letter was posted a week ago.
2) The letter arrived to my work yesterday.
3) I went home from work (yesterday).


Thank you.

Your sentence is grammatical, but Rover's sounds far more natural (and is also grammatical).
The use of the past perfect tense is not mandatory simply because you can use it in a certain place. It's often unnecessary and ponderous.

Remember to use "at work" not "to work" in this context.

The correct preposition is always difficult for learners and can entirely depend on the verb that precedes it.

I arrived at work at 7am.
The letter arrived at my workplace at 2pm.

I am going to work at 6am tomorrow.
He's not going to work today because he's sick.

Look at these two though:

As soon as I arrive at work, I'll make a coffee.
As soon as I get to work, I'll make a coffee.
