[Alan]

This means you must be quicker - you must do things more quickly because if you don't, we are going to be late for work.

Why I can't use: I'm telling that you must quick up or...?

[Torsten]

Hi Kyd,

Welcome to english-test.net and many thanks for your question. You can't use 'quick up' because 'quick' is not a verb and the phrase 'quick up' does not exist.
Regards,
Torsten
