Boss tells his workers:
(1) You are to finish this project by the end of next month.
(2) You are to have finished this project by the end of next month.
After a while, one of the workers tells his boss:
(3) You said we were to finish this project by the end of next month, but we encountered problems and so can't do it in time.
(4) You said we were to have finished this project by the end of next month, but we encountered problems and so can't do it in time.
Are (1) & (2) both natural?
Are (3) & (4) both natural?
Hope to hear both Britain and American speakers. Thanks!
