At the very least, you can file whatever grievance procedures there are internally to focus your employer on the fact that you view the policy as offensive to your ethnic or racial group and lobby to change that policy. If the policy creates an atmosphere in the workplace, which impacts on your work life as a member of a specific group, you may have a human rights or constructive dismissal claim, which, in Ontario, can be combined in one civil action.
Sometimes employers will respond to a complaint of racism by starting a workplace investigation. Sometimes they do this honestly, not knowing what had transpired and genuinely wishing to find out what occurred, get to the best result and remediate.
Other times it is a delay intended to develop their own statement of defence and get their public relations plan in place in advance of any statement of claim being issued or of the public learning of the issue. If it is the latter, strategically, you should not permit that time and come out quickly with your statement of claim and own the media campaign if any, before the employer’s position is entrenched and it has had time to remediate its reputation.
You should also investigate the background of their chosen “investigators” to learn if that person has expressed any opinion on the topic.
In one recent public dispute about anti-Semitism, the investigator had historic tweets indicating a bias. The fact that the investigator is a lawyer does not, as they will claim, guarantee that they are objective and open minded.
In my experience, many, perhaps most, investigators are hired guns, looking to be reappointed for further lucrative investigations, which require little legal knowledge and skill. Their reports have no weight with courts as they are inherently hearsay and the judge must and will come to his or her own determination after observing the witness testimony.
If the investigation report is against you, you should respond immediately with the following: note any bias of the chosen investigator, their historical financial involvement with that employer, witnesses they failed to interview, misapprehensions of the facts or law, the inherent improbabilities of their conclusions and the fact that they disregarded the evidence of those witnesses whose evidence they did not list.
An employment lawyer should assist you with that rebuttal. But remember, much as an employer may try to wrap themselves around that report as it sanitizes its conduct, the findings of an investigator are totally irrelevant as the court comes to its own conclusions.
I find that internal employees, in human resources, will get a better result and more quickly, since they have no financial incentive to drag the process out, and already know the players and the company’s policies. In the rare circumstance that an external investigator is desirable, use a retired judge who has credibility and is trained in ascertaining facts and who will have the respect of all stakeholders.
