<prompt> Human: Heres the situation:I am taking a new job and my first day will be April 3rd, 2017.I become vested keep my employer match for my 401k and become eligible for the employee pension on March 31st, 2017, which is three days before the start date at my new job.Ive always submitted a two-weeks notice in the past, but my current boss can be unpredictableunreasonable. We have a bit of a history and I dont necessarily trust that he wont just tell me to kick rocks when I give my two-weeks notice.I have a friend who works in HR at my company and he let me know that employees are usually blacklisted when they dont give a two-weeks notice. I dont plan on returning to this company, but Ive made a habit of not burning bridges in my professional life.Heres the options Ive come up with:1. Roll the dice and submit my two-weeks notice. This is putting about 9k of employer match on the line, plus any additional pension s in the future.2. Provide a one-weeks notice, which is the amount of PTO I currently have accrued. With this option, I run the risk of being blacklisted and I cant guarantee that they wont just fire me and not honor my PTO; this would result in being blacklisted and losing my matchpension.3. Show up on March 31st and tell them that I wont be back, ever. This would definitely result in me not having future with this company.Additional question:If I submit a two-weeks notice, identifying a specific date as my last day, can they terminate me with an effective date other than the one I submitted on my two-weeks notice? The employer is in the state of Iowa, if that makes a difference. My HR buddy wasnt sure if he could answer this question accuratelyAny advice or opinions would be greatly appreciated. If you have any follow up questions, Ill be checking this pretty regularly and will respond as quickly as possible.This is also posted in rAskHRThank you in advance for your help!  <response>: Start by assessing whether you can move your start date forward a week or two. Feel free to explain the vesting concerns and your desire to give two weeks notice to your employer. Those are perfectly reasonable concerns. No employer will think youre crazy for being uncomfortable with leaving 9000 on the table.If you cant, then consider that you already have a new employment offer, so its not like you need the recommendation immediately. You can build up both experience and reputation at the new job. Being blacklisted from rehire isnt a particularly terrible thing if you dont plan to use them as a recommendation or reapply in the future. How does this negatively affect you?Im normally against burning bridges too, but you know your boss better than we do. If he seems a little unstable, better safe than sorry.
