Worst work Culture in IT Department - Software Developer Boston Scientific Employee Review

They have hired certain managers and Tech leads who do not have much knowledge .They dont know how to deal with their US counterparts, they dont know how to behave with associates working under them .There is a tech lead in IT department who bullies associates and start shouting on them and the funny part is if you raise the issue , nobody is there to listen you , infact they can do stupid politics and compel you to resign from the company. If you raise the issue with managers or HR , then you might be at the risk of loosing job. They give stupid papers on which they call as 'PIP ' and gives you lame reasons on that sheet that why they are putting you on PIP.
