Part timers?
Or students?

If students they should be able to speak at least a little bit of english.
If not how did they get the job in the first place.

Show them how to do it, assign them to one of the staff and ask them to help them out.
That's the fastest way, then when they know the basics already ask them to go solo.
If you think they don't really know it yet, just ask them to do everything.
