I work in clinical pharmacology. I have a master's degree in pharmacology (bachelor's degree in molecular and cellular biology).
The work itself is not exciting for me. I went into it wanting to do more science; you'd be surprised how little science is involved in my job! It's more about knowing how to use the software to analyze the data (follow our SOPs) and knowing how to code in SAS to make the reports (also following SOPs). However, the environment I work in is the real problem. Everyone is so stressed out and miserable and it makes it so, so hard to work. People are always trying to save their ass, so they will throw everyone else under the bus to save themselves. No one takes responsibility when something goes wrong and everyone points the blame at everyone else.
I was promised a path to progress my career (and do more science) which remains unfulfilled. Management admits I have done nothing "wrong" or "bad", they just don't want to develop anyone's career unless it is very convenient for them and in my case it's not convenient enough for them.
On top of all this, I am definitely underpaid for what I am doing. I know for a fact that I am only getting half of my market value. I've discussed this with my direct manager and the head of my group and got some ridiculous responses.
All of that in consideration, and the fact that I cried 3 mornings last week on the drive into work (dreading going there), it's time to move on!
