Workplace practices and procedures are often contradictory. The best laid plans will often change at the last minute for an entirely different approach. Supervisors have their favorite direct reports and tend to forget about the others. Recognition for good work is fleeting, especially if you're not a chosen favorite. Being overlooked for promotions or general considerations will happen. Departments can sometimes be run like a medieval fiefdom- where standard company policies and procedures are ignored and the word of whomever is in charge becomes law. If you have a medical condition or disability, be aware of your rights- the system in place for accommodation requests was overly complex and inflexible. Working with other, different teams will happen often, though some on those teams will not assist, leaving you to either do their work or find a way around it. You will work a lot and you will lack a work/life balance.
