So, the injured teachers and school workers could bring a case for intentional assault or possibly even a civil rights case against the sheriff’s department. Of course any state actor responsible for an injury has some protections under sovereign immunity for their misconduct. (Sovereign immunity usually is not an issue in workers’ compensation)
Besides being compensated for physical and mental injuries, an employee who is intentionally injured in an active shooter drill may have employment law concerns as well. In my experience, an employer dumb enough to let their employees be assaulted would be bird-brained enough to retaliate against an employee who made a workers’ compensation claim for the injury. That same employer would probably also retaliate against an employee who reported safety concerns to an outside agency like OSHA.
But purchasing new machinery is expensive for business. (Or it cuts into returns for wealthy investors.) Control software is seen as a cost-saving hack.
In the case of the Ethiopian Air crash 157 crew members and passengers lost their lives. Thankfully not all accidents from using 2019 software to control 1969 machinery will be as fatal as the Ethiopian Air crash. But nonetheless accidents from industrial machinery can be gruesome and disabling even if they don’t make international news.
Obviously injuries caused by this slapdash industrial technology would be covered under workers’ compensation laws. But other laws would certainly come into play as well.
Employees injured on the job by defective machinery can also bring a negligence case against the manufacturer of the equipment. This so-called third party case could be worth substantially more than a workers compensation claim. But in a case involving modern software controlling old machinery, there could be a dispute over who was at fault. Producers of older technology may also be able to defend negligence claims based on a statute of repose defense which can limit claims for injuries that have yet to happen.
