Question

Which sentence is most appropriate way to ask co-worker or your boss in business?
1. Can you bring me up to speed?
2. Can you bring me up-to-date?
3. Could you update me?

If you have other suggestions, please let me know and I appreciate it.

Answer

Yes, all of those are appropriate phrases, but you'd normally also refer to the topic in question. For example

Can you update me on the XYZ project?
or
Can you bring me up to speed on what's been happening with XYZ project?

Another expression which comes to mind is 'fill someone in on something'

Can you fill me in on the XYZ project?
