Probably not. You do not need a firm with hundreds of lawyers,
most of whom have never been to court and most of whom have never
represented an individual plaintiff in any kind of litigation.
Generally, large firms (100 or more lawyers) that are well
known in your area or nationally will be defense-oriented firms.
These firms are not those accustomed to representing individuals
or organizations in whistleblower cases and will often have a
policy against taking on such cases. Often, a number of big law
firms in any one city will represent the largest employers and
corporations.
Except for a few firms that regularly represent plaintiffs,
most large law firms do not normally handle cases on a contingent
fee basis, where the plaintiff pays legal fees only if the case is
successful. Instead, corporate law firm clients pay their
lawyers each month, at hourly rates of $200, $300, or more,
regardless of the outcome of the case. Most whistleblowers cannot
afford these kinds of legal bills.
You will need to be extremely cautious in approaching any large
firm or their lawyers to represent you or to help you find a
lawyer, particularly in cities where the defendant is located or
does business. With large corporate law firms, it is very likely
that at least one lawyer in the firm has previously represented or will represent
in the future--the very defendant that you want
to sue.
