persons, premises, and equipment that might otherwise be caused by their sudden cessation of work.
The Board first applied this “reasonable precautions” principle to rank-and-file employees in Marshall Car Wheel & Foundry Co., Inc., 107 N. L. R. B. 314, 315 (1953), enf. denied on other grounds, 218 F. 2d 409 (CA5 1955). There, employees at a foundry walked off the job at a time when the foundry’s furnace was full of hot molten iron, threatening severe damage to the employer’s plant and equipment. 107 N. L. R.

General Chemical Corp., 290 N. L. R. B. 76, 77, 83 (1988). Similarly, the Board held that the strike conduct of security guards whose walkout exposed a federal building’s occupants to “imminent” danger was not protected by the NLRA. International Protective Servs., Inc., 339 N. L. R. B. 701, 703 (2003).

So the Board has also repeatedly held that employees have no duty to prevent the loss of perishable goods caused by their sudden cessation of work.
