Wireless Emergency Alerts (WEA) are governed by the Federal Emergency Management Agency (FEMA) within the Public Safety and Homeland Security Bureau. FEMA administers the Integrated Public Alert and Warning System (IPAWS), which is a public safety system connected with participating wireless carriers. Organizations such as county, city, state and federal public safety agencies can register to be an alerting authority in IPAWS, and this allows them to broadcast WEA messages through participating wireless carriers to user devices supporting WEA.

Works Council

A works council in Germany is an employee elected body that represents the interests of employees in a business. A unique right of a works council regarding social matters, such as company code of conduct rules and the introduction and application of technology, is called comprehensive codetermination. This means that an employer cannot implement certain social measures without previous agreement from the works council. Technology policy is considered a social matter, so the works council must agree to the provisions of the policy before it is implemented. Failure to secure an agreement can result in costly arbitration for the employer and workers frequently have an advantage over employers in arbitration cases.
