I think it means that they feel that they can do it safely without it. It also saves them from having journalists taking photos. Your security team and HR team must be really good lay-off some many people without causing violence, law suits, data leaks. I can easily imagine that if 50% of people present in a office were laid off some would start a protest within the office which could degrade into some violence, damages and law suits. Also, having the HR systems automation must be really on par to revoke access correctly to so many people.
