This rings especially true for me at my current company. Everyone says around here that the most important skill you can learn is "expectation management".

When given a task that is supposed to take 1 week, the absolute worst thing you can do is complete it in 2 days. Actually, 1 day, or 1 hour would be even worse.

Doing that will only open the flood gates to dump an ever increasing workload on you, while receiving zero recognition.

Sounds like you need to make your current company your former company.
