Is there any way to push back against really ridiculous deadlines when high ranking SES have expectations?

Looking for advice.

I am known to be fast and pretty good at what I do at work. This has lead to me becoming someone that gets randomly plopped onto a project in my division for a short stint to fix major fuck ups or employ my skills that the team in question maybe doesn’t have.

I don’t mind it in principle, but it keeps leading to deadlines that are extremely difficult to meet.

For example, not too long ago I got given to a team for a week to write a paper. It was conveyed to me as a 5 day task, but very quickly I realised it would take at least 3 weeks for any normal person and really should be done that period.

I was told the SES expected it within 4 days and to basically stfu and get it done.

These kind of expectations are making me extremely tired and also stressed. Not to mention, my day job changes constantly because I never know where I’m going to be teleported to next week to assist.

I don’t know how to successfully challenge these deadline expectations *when* there is SES involvement/hard deadlines in their head.
