The correct answers are; mental health issues, Family Medical Leave Act, child labor laws, and hostile work environments are specifically covered by the federal government.

Explanation:

In the United States, workers are under numerous regulations by the federal and state laws regarding their rights.

Family Medical Leave Act is given to employees that meet certain guidelines. They can use this leave and not lose their jobs while out of work if they are being treated for their illness or disability.

Mental Health issues are covered under both federal and state laws. The federal government helps to protect employees with their privacy and discrimination. Two laws for mental health issues in the workplace are  MPHAEA and ADA.

Child labor laws are covered by the federal government also. The law is the FLSA/Fair Labor Standards Act. No child under the age of 14 can legally work in the U.S, unless the parent is the employer or it is an exempt job such as delivering newspapers.
