I disagree with the prior poster insofar as he's suggesting that malignancy is in the eye of the beholder. It's not an individual perception kind of thing. If a program is malignant, most or all of the residents feel the brunt, not just one being "singled out". It's an objective standard. Basically it's a culture of abuse. Residents are in a very precarious position. There are rules governing how they may be treated but not a great deal they can do about enforcing these rules without jeopardizing their position or program as a whistle blower. They are the low person on the totem pole, and can be overworked, berated, scutted out, abused at the whims of the program, the attendings, the administration. So there are places that treat folks better or worse, based on this lack of control. Some places treat residents as the up-and-coming professionals they are and really try to emphasize the learning opportunities, others you will find attendings and residents having a very collegeal time always joking and residents covering for each other as long as the work gets done. Others programs see residents them as annoying little cogs in the hospital machine and treat them accordingly -- violating hour rules, seeing nothing wrong with berating people publicly, keeping them scutted out and not doing anything remotely educational. It is this latter that can fall into the malignant category. It's usually a culture that stems from the higher ups -- if the chairman or PD is a SOB, the chief residents will probably be act accordingly (s^&t flows downstream) and you will end up with a malignant program. So basically malignant is a culture which encompasses components of most of what you have mentioned in your initial paragraph (give or take the basement membranes). It's not a pleasant place to come to work. It doesn't have to be that way, but some places foster that culture, and there is very little a resident can do about it besides be a whistleblower/whiner, get him/herself kicked out of the program and maybe get the program in trouble. None of which are great options.
