You should always be aware of your rights as an employee, especially if you work in a job with more than the ordinary level of danger to it. If you do and your employer isn't providing first aid and Occupational Safety Hazard Administration training, ask them why not.

If you're an employer, even a small one, you'll need to keep a weather eye on all aspects of employment law. It changes often, especially in regards to employee rights and privileges, and it's best not to be caught out when these changes occur.

Foreign workers are a special case in the American legal system, one administered by a fairly large set of employment laws. Whether you're a foreign worker or an employer of foreign workers, however, you should make sure you understand these laws, and keep an eye out for changes.
