It seems that workplace retaliation by managers against employees who complain about their superiors' violations is almost part of human nature - at least for some people, who feel both angered and threatened by the complaints against them, and can hardly restrain themselves from seeking revenge, by making their subordinate's life harder in so many obvious and not so obvious ways, such as increasing work load, issues bad performance reviews or warning, attempting to relocate them to a less desirable location, trying to demote them or false accusing them of misconduct.
There are different ways in which the law addresses retaliation, some of which are more effective than others. Documenting evidence of retaliation and having witnesses to at least some retaliatory actions can be critical in either proving a retaliation claim or making it stop.
