When several employees are showing signs of sickness and the company would like to make sure that others in common areas are not affected.

Est-il possible que répéter votre question en arabe ou en français?

send those "several employees"

to doctor you know, to know the results and to take action.

No.   The situation leading to shut down has to be avoided at any account.   As an emergency, the health wing of the Organization may check the employees and give proper care including preventive care.    Those really affected has to be given off.   In emergency, the organization may hire skilled workers.    Life blood of any Organization is that it keeps on moving, and every action must be directed to keep moving the rolling wheels.

I say "yes"!

Your health and theirs are important.
