Although completely illegal, it is almost natural for managers to feel both threatened and angry when an employee brings a complaint about the safety issues in their department. The unlawful workplace retaliation can take many forms - from false accusations of misconduct and violation of policies to administrative leave, suspensions, demotions and even termination.
If you suspect that your employer has engaged in retaliation campaign against you and is trying to build a paperwork to drive you out, it's important that you contact an employment attorney to discuss what legal and practical steps you can take to possible prevent your termination or make sure that you have a stronger retaliation claim later, if and when you decide to bring a claim against the employer.
