According to the Labor Contract Law, the workplace belongs to the legal content of the contract. If the company requires employees to change their offices, they should consult with the workers. If both parties reach an agreement, they can change the contract and continue to perform it; If no agreement can be reached, the company shall notify the employee 30 days in advance or pay an extra month's salary to terminate the contract, and pay the economic compensation of one month's salary every year according to the employee's working years.
According to the information you provided, Xinbao Technology Company did not inform employees to move their offices 30 working days in advance, nor did it formally issue a notice. This may violate the provisions of the labor contract law. As for your "disguised layoffs", I'm not sure. For more information, please consult your local labor bureau or lawyer. I hope my answer can help you.
