If you are a partner in the store, you have the right to lock your store door. This situation is not illegal. However, if you have any problems with other partners, you should communicate and solve them in time so as not to affect your business and cause losses to yourself.
Shareholders have no right to lock the door and not operate. If the company wants to suspend business, it needs the approval of the shareholders' meeting or the shareholders' meeting, and it needs to apply to the administrative department for industry and commerce and other organs for suspension. Only after obtaining the approval of the relevant authorities can the business be suspended.
This may be an illegal act, even suspected of committing a crime, interfering with production and operation, and disputes between shareholders or between shareholders and the company should be resolved through consultation first. If negotiation fails, it shall be settled through litigation, and improper means shall not be taken.
