Hi!

I'm filling in a job description and I'm wondering if it's appropriate to write in the following way?

"The language of workplace communication was Spanish. English was used infrequently, mainly in written form in work with foreign clients or domestic clients with an international orientation."

1) Is this text grammatically correct?

2) Could this information be expressed more elegantly/clearly?

Thanks a lot for your help!

Cheers,

Allan
