You work as an analyst in the marketing department for Springfield International (SI). SI uses a weak matrix to develop new services. Management has created an extremely competitive organizational culture that places an emphasis upon achieving results above everything else. One of the project managers that you have been assigned to help has been pressuring you to make his project your number one priority. He also wants you to expand the scope of your work on his project beyond what your marketing manager believes is necessary or appropriate. The project manager is widely perceived as a rising star within SI. Up to now you have been resisting the project manager's pressure and complying with your marketing manager's directives. However your most recent interchange with the project manager ended by his saying "I'm not happy with the level of help I am getting from you and I will remember this when I become VP of Marketing." How would you respond and why?
