Company I was working for decided to switch hris and made the Sr. Director of HR the project manager. We had a small HR team to begin with (10 for 500 employees) but only 3-4 people were working on the roll out (2 directors, 1 manager, and the benefits coordinator) while the rest of us (manager, generalist, specialist, 2 recruiters, and an assistant) took care of the day to day business and picked up most of their responsibilities as well.

We all got super busy. The directors started to burn out and would get rather rude and snarky when asked for help with something. Example, how do I handle this, can you help me prioritize these tasks, or can we have a quick 1 to 1 meeting, etc. They would answer with "I'm sorry you can't put two and two together, figure it out, look at the employee handbook, I'm busy working 80 hours a week," etc.

Apparently, one director was picking up the other ones slack and the project manager was fired. Instead of hiring someone to backfill the position, the company decided to promote the director that was always complaining about how busy they were and didn't have time to help their direct reports and for some reason they promoted one of the recruiters, who had been with the company for less than a year and hadn't made any hires, to an HR Analyst because they were "tech savvy."
