<prompt> Human: Original thread so I accepted the other companies offer and gave my office manager a two week notice. I left this evening and got a call from the owner of the company telling me that a two week notice was very unprofessional and that I need a one month notice as its professional courtesy. I feel like I just burned a bridge and its made me feel so much worse. Ive never even heard of a one month notice.  <response>: Two weeks is standard. In my industry Project Managers and higher-level management will sometimes give more if the split is amiable and some transition time is required. Do not feel obliged to give more. The fact they all the sudden came up with 50 more money should tell you something about how they run the business and view their employees. Congratulations on the new gig!
