Before you call this a possible massive cockup, you need to look at the rosters for the two pilots, and how many hours they have been flying monthly for the last years, how many (or few) days off/leave they have had, night duties, etc.
EK management is sitting on a big box full of smelly rosters.
If it is legal, it doesn't mean it's safe.
First actions by management is to block access to the names of the crew, and their rosters. Most likely so that the above mentioned questions cannot be asked or answered.....
