三方毁约真正卡人的从来不是那笔违约金，是**顺序**：原单位的书面解约函没到手，学校一般不受理换新三方；新三方没换成，新单位的入职手续就办不了。三个环节串行，其中两个完全不由你控制。 所以这个工具算的是**倒排工期**：填上计划入职日，代码跳过周末与法定节假日，给出每一环的最晚完成日和最晚启动日，并直接告诉你**来不来得及**。来不及的时候，能压缩的只有第一环（别等对方「研究一下」），第二三环压不动——那时候更现实的办法是改入职日。 违约金那一头只做换算：相当于几个月工资、占首年年薪多少、按新旧 offer 的月薪差多少个月回本。回本期这个数比金额本身有用得多——它把「五千块贵不贵」变成了「这次跳槽的经济账多久打平」。 至于「违约金不得超过 5000」这类流传很广的说法，**这里不会给你数字**：那些来源是各地各校不同年份的规定或某一版范本，你要的答案只在你签的那份协议原件和你们学校就业指导中心那里。工具给的是该核哪三件事。$2 解锁协商话术、解约函与沟通模板、以及档案与报到证的处理顺序。What actually blocks a tripartite-agreement withdrawal in China is not the penalty — it's **sequence**. Without the original employer's written release, the university usually won't issue a new agreement; without that, the new employer can't complete onboarding. Three serial steps, two of them outside your control. So this tool computes the **backward schedule**: give it your intended start date and the code, skipping weekends and public holidays, returns the latest completion date for each step, the latest possible start, and whether there is enough time at all. When there isn't, only the first step can be compressed; the realistic alternative is moving the start date. On the penalty it does conversions only: how many months' salary it equals, what share of first-year pay, and — using the gap between the two offers — how many months until it pays back. That last figure turns "is 5,000 a lot" into "how long until this move breaks even". As for the widely repeated claim that penalties are capped, **no number is given here**: those figures come from particular universities, provinces, years and template versions. The answer exists only in your signed copy and at your university's careers office. What this gives you is which three things to check. $2 unlocks negotiation scripts, release-letter and message templates, and the order for handling your file and dispatch certificate.
与原单位的协商话术（三种态度分别怎么应对）、解约申请与沟通模板（微信／邮件两版）、学校流程的问法与该问谁、档案与报到证／派遣证的处理顺序，以及最后一节：这次决定五年后回头看会怎么样。Negotiation scripts for three kinds of employer reaction, request and message templates (chat and email), what to ask the careers office and whom, the order for handling your personnel file and dispatch certificate, and a closing section on how this decision reads five years out.
本工具不提供法律意见。三方协议的效力、违约金金额与是否可协商，以你签署的那一份协议条款为准；各校对改派、换发三方的规定差异很大，请以本校就业指导中心的答复为准。工期为**保守估计的预留天数**，不是任何学校或单位的规定时限，实际耗时取决于对方配合程度。已实际到岗入职的情形通常已转为劳动关系，适用规则不同，涉及金额较大或已产生争议时请咨询律师或当地劳动仲裁部门。请勿伪造材料或提供不实理由——解约函、离职证明与学校材料都会被核对。你填写的内容不入库。This is not legal advice. The validity of a tripartite agreement, the penalty amount and whether it can be negotiated are governed by the copy you signed; universities differ widely on reassignment and reissuing agreements, so treat your own careers office as authoritative. The durations are **conservative buffers**, not rules or guaranteed timelines, and real elapsed time depends on the other party. If you have already started work, the relationship has usually become an employment one with different rules; consult a lawyer or the local labour arbitration office where amounts are significant or a dispute exists. Do not falsify documents or reasons — releases, certificates and university paperwork all get checked. Nothing you enter is stored.
