**When it was my birthday I made a big cake for all my coworkers.**

I'm at the bottom of a big company. There is a lot of different functions in the company, though most of the employees work at a computer. If I'm referring to everyone at the company, is it correct and natural to use "coworkers"?

When I search on Google there is way more hits for "for all my colleagues" than "for all my coworkers".
