Colegue could not find data when running a very important report.
I did some research and found out that there was no data for for the month they searched . They ensured my boss that they did upload the data and that the program just does not work.
I spent two days of work trying to find out what the problem could be, under boss's pressure.
Still there was no data in the database or a record that there was ever any for that month.
The deadline passed. We got fined and only after that the colegue reilised that she had never generated the data, so there was not even data to upload.
Now it is my fault cause I never told her that she needed to do that.
I am the new guy and she has been working the same job for 7 years now. Like WTF
