An employee has a dispute with his boss, his boss gives him a hard time. The employee engages a private law firm to assist in the negotiation process to smooth things over with the boss. The Union is useless in this matter, hence the employee hired a Lawyer.

Later, the employee finds another job, and gets the private lawyer to negotiate a termination payment/settlement with the current employer the same one where the boss was giving the employee a hard time.

Are both, or one of the above situations Tax Deductable? If so, under what Reference is it claimable?
