Pros
The colleagues I worked with were the only reason I stayed as long as I did.
Cons
You'll be forced to absorb the responsibilities of anyone who quits or is laid off, even if they are your manager. You will not get a salary increase for the incremental work, and if you successfully manage the additional workload, you won't get a promotion, they'll hire a consultant, who you will train, and then report to. When I put in my notice they tried to persuade me to stay by saying they'd promote me two levels on the spot. I had been vocal about wanting a promotion for 2 years but was skipped over even though my performance reviews were positive. My areas to improve included nonactionable things like "Keep up the good work!" It felt like a slap in the face.
