I plan to file a lawsuit against my company. If I describe the backstory and situation here and ask for advice, will it affect the lawsuit? I am yet to file it but I am meeting a lawyer this week
We don't know.
Most folks here are not lawyers. And the ones who may be, are not here to offer professional services. Thus, it's likely that you may not get an objective answer.
You may however seek general advise without revealing much details/using anonymized information without revealing your or organization's identify.
P. S.: You may need to create a new Stack Exchange account which doesn’t reveal any personally identifiable details.
