As always, document your efforts and keep good records. Encourage ethical behavior at all levels of your business. Recently, the biblical version has staged a remarkable comeback. Ethics in the work place, both with intra-company matters and as it relates to the outside world, is the only rational approach for the conscientious business person. Good ethics means good business.
Juries love to punish the arrogant and vindicate the innocent, no matter where the courtroom is.
Incidentally, it is relatively useless for business owners and management to preach ethics and fair dealing, and practice infighting and management by intimidation. Teach by example. Be familiar with alternative dispute resolution. If your business has done everything right, has kept its documents in order, attempted to resolve disputes, acted ethically, and still cannot reach resolution, that does not mean that the courthouse is the only destination. Remember, unreasonable people make the most persistent plaintiffs, so if someone cannot be placated informally, they may become even more troublesome in litigation.
