Every grammar book has a section about Future Perfect tenses, but as this article and the comments point out, I don't really hear this type of language constructions from Americans (including in an office setting). Would be really nice to know what a native speaker would do/say/use in a normal conversation in situations like these (even if it's not grammatically correct or has not exactly the same meaning):
- The film will already have started by the time we get to the cinema. [example from a British Book]
- The company will have spent all their training budget by the end of the month.
- They won’t have arrived by the time you get there.
