Salary not always great
A new environment is more challenging, while you're at it you want to move, there's bottleneck on Managers not allowing you to grow and keeping you stagnant on the same role for their benefit. As an individual you need to understand that you're there to serve at the same time not neglecting your growth and aspirations.
Long hours, working outside your prescribed normal hours, taking more responsibilities than what anticipated.
