It is illegal for an employer to retaliate against an employee for making a complaint that is protected by law. Protected complaints include discrimination, retaliation, sexual harassment, wage theft and various forms of whistle blowing for illegal and dangerous conduct.  It is retaliatory for an employee to suffer a demotion, termination, pay cut, schedule alteration or other hostile behavior in response to issuing a protected complaint.  Do not be afraid to enforce your rights because anti-retaliation laws are designed to protect you.
