Lack of empathy, promotions and raises but abundance of work and complains - Consultant IQVIA Employee Review

IQVIA has suffered from a drastic short-staffing that I haven't really seen in previous years, which has resulted in smaller project teams than needed and people taking more projects that they can successfully handle. Management feels that by saying "we need to be more efficient" or "simplify the approach" they solve this, and on top of they do a bunch of last minute non-project related urgent requests. Many times I have worked until early hours of the morning sending deliverables without a single "thank you for staying late" (I even got once a "lets discuss before 8:30AM" response in the early morning for an email I sent at 2:00 AM). The expectations they have are sometimes not reasonable, and there is a lack of empathy from upper management which very rarely recognizes successes but is always prompt to complain about the smallest things. I constantly feel that even doing my best and sacrificing my work-life balance it is never enough. I have not received a raise in recent years, promotions are pretty much frozen, and in all my years here I have never received my bonus a 100%. This is a shame as projects are interesting and clients are usually nice, but poor management really poisons the well and pretending that there are no issues is not the way to address them nor improves morale.
