If your company is forcing you to share a room with someone, they don’t have your best interests at heart. 

Sharing a room with someone is best done with your close friends and family. You’re comfortable around each other, have a sense of each other’s personal lives, and there is a huge level of trust. Sure, you might sign up to sleep in a hostel with strangers, but there is safety in numbers. A one-on-one room-sharing situation might leave you vulnerable. This is especially true with coworkers. 

The coworker relationship is a special one. You likely spend a lot of time together, but you don’t know everything about each other. You might not even hang out outside of a work context. There are probably aspects of your life that you would rather not share with them. You certainly wouldn’t want to share a room with them. Even if you are comfortable with each other, it’s a huge liability for the company, not to mention a display of cheapness. But that doesn’t stop some employers from taking the risk on behalf of their employees.
