When I first started in the company I was specifically told by my boss who is the owner that they wanted someone long term and who wasn't going to jump ship. I nodded and said I understand that but after 9 months working here my boss has treated me pretty unfairly - conditions have worsened between us to the point that I am now leaving. How can I perform my duties to the best of my ability when I'm 80% certain he is going to make the two weeks a living hell?
You don't owe him anything! and remember you and your boss are not in a romantic relationship, but rather working together as a professional.
Meet him face 2 face and tell him you have made this decision with much of thought. Thank him for everything he has done for you, and let him know you hope to see his support and encouragement for the remaining 2 weeks.
Worst come to worst, you're gonna have 2 weeks of hard time in your office, but eventually you will overcome with it! :)
P.S try not to criticize him by telling him you have been treated unfairly. Doing that would guarantee a 2 weeks of hell!
I would proceed with caution and look out for you.
I would say you should consider not giving a two weeks notice. I am not saying I recommend it, but it's worth considering depending on the situation. Your mileage may vary.
At my last job I was certain of the same situation when I was leaving. I tried to be professional and give 2 weeks. Sure enough it was hell, and then my boss excused me just a couple days refusing to pay me for the remaining time on my contract. I had already given the start date at my new job so I was out of almost 2 weeks salary. If I could go back, I wouldn't have given a notice. My boss was a spiteful person so there was no way they were ever going to be a positive reference anyway. So you have to ask yourself :
What do I have to gain/lose by giving notice?
I would start with:
"You are probably going to think I am nothing but a disloyal low life and a horrible person".
The goal of that statement is for him to disagree with you, so all of a sudden you are not a horrible low life, but a good person.
Then when talking with him you need to use some key phrases:
- Thank you so much for this opportunity
- I hate to be leaving but the new opportunity is too good to pass up.
- Over the next 12 days I will give you 80 hours of the best work I can. I will do this to be fair to you.
No matter how you felt you were treated, he wants to feel like you were treated well. Fine, play into that, who cares. Say these things deferentially.
At no time mention that you were treated unfairly. At no time attempt to fix his work space. The story you are trying to sell is that the only reason you are leaving is because the new opportunity is to good to pass up.
He may ask you for a number on what you have been offered at the new position. Do your best not to give a number. If he really corners you, you can simply decline to answer or if you must answer give a range that is very high. For example lets say you are being paid 50K now and the new job has offered you 70K. I would say I'd say something like: "I value the salary and new benefits to be in the 140K to 150K range".
This is not lying. Why? Because you value of not putting up with his attitude at 70-80K per year.
He of course will be shocked, and of course you can reply: "I know how could I turn down such an opportunity"? Now he is on your side.
Your goal is to get out of there amicably as possible.
