My coworker got one of the best assignments at work seemingly without even working for it. I wish I could get better assignments like that!
My coworker was given a great work assignment this morning. It seems like she did nothing to even deserve it. I wish I could get such great assignments!

I hate when that happens.  Things always seem to go that way.

I know it's really frustrating. I don't know what I should do at all.

All you can do is just keep doing the best job you can and hopefully someone will notice someday.
