@Linkat,
What would their answer be if you asked them why if your understanding the deadline is a month away, why it's changed to now, and is involving disciplinary action.
I think that's more than a fair question.
It sounds to me like a mass communication was put out putting the due date at the end of the month, but that's the date it's got to be at the final person/department.
If data has to be passed through several departments, of course it will take time for each stage to be rolled up to the next level.
In that case though, the final deadline should have been communicated to the 2nd to last person, and then each stage along the path could have been given their own deadline to get to the next step.
