setting out the violations of the law allegedly committed by the respondent. While the Act requires that the original unfair labor practice be filed within six months, there is no comparable statute of limitations for issuance of a complaint. The complaint may also be amended in some circumstances to include other alleged violations of the Act not specified in an unfair labor practice charge. The Region will usually renew its attempts to settle the matter after it has made the decision to issue complaint but before it has actually done so. It can settle unfair labor practice charges unilaterally, i.e., without the agreement of the charging party. The Board draws a distinction between formal and informal settlements, i.e., those that call for issuance of a formal Board order and those that do not. A party unhappy with the Regional Director's settlement of its unfair labor practice charges can appeal a formal settlement to the Board itself, which must approve any formal settlement in any case, but can only appeal an informal settlement to the General Counsel. The Board will set aside an informal settlement agreement if the employer violates the agreement or commits other violations of the Act after the agreement. The Board can, by contrast, enforce a formal settlement like any other Board order by petitioning the Court of Appeals for an order enforcing it. The Board will also accept non-Board settlements, in which the charging party withdraws its charge in return for promises from the other side. The Board is not, however, obliged to accept the parties' settlement agreement or to allow withdrawal of the charge. Interim injunctive relief If the General Counsel believes that there is cause to issue complaint, then he can seek injunctive relief from a federal district court under Section 10(j) of the Act. Injunctive relief is usually ordered when necessary to preserve the status quo pending the Board's decision on the complaint or to prevent employees from suffering irreparable harm. Any injunction lapses once the NLRB issues its decision. The General Counsel does not have to prove that the allegations in the complaint are well-founded, but only that he has some evidence, together with an arguable legal theory, to support his claims. Even so, the General Counsel rarely uses this power to seek relief while complaints are pending, other than in secondary boycott cases, in which the Act commands the General Counsel to
