Could someone what do they mean by this question please.How does their work force reflect their global strategy?

What is the context?

Which part of that question don't you understand?

Whose workforce?

We are talking for example McDonald's how does their work force reflect their global strategy?

What is their global strategy?

Its McDonald's

The workers at my local McDonald's have nothing to do with the McDonald's in 115 different countries in the world.

Their workforce is likely very diverse in terms of religion, ethnicity, gender, etc.

What does that say about their global strategy?

Does it imply that McDonalds would like to continue expanding into more countries by promising the local population jobs?

Think about McDonalds objectives and remember they're in it to make money.
