Pros
If you manage to survive longer than a month, you can consider yourself to be stress resistant and tough. There are no pros for the AP position.
Cons
The entire department is chaos, no one knows what they are supposed to do, 3 out of 4 managers are completely clueless and when put on the spot, they will dump all responsibilities on you. You will not get support from manager, you will not get training, you will learn by making mistakes and being blamed for it. Managers and HR are intrusive, they will monitor your personal life, your breaks, doctor appointments (I had to wait a week before being given the time off and I was asked to provide the reason). Managers will use scare tactics to make you work overtime and weekends (extending your probation period, shouting at you, asking you if you really want this job). Workload is unbearable, you will be doing the work of 2 people, which means that you are bound to forget to do things or running out of time, you will be blamed and asked to provide full details on why and how you could have possibly forgotten something, while all the things you are doing well are completely oblivious to the management. The department is badly organised, management is not aware that computers have been invented, you will print everything and archive it in a box, there is no database, only the boxes in storage. I have spent hours looking for a piece of paper which could have been scanned and stored in a database. Thermofisher is not a green company, you will spend your days printing. I worked for 7 months and I know of 6 people who suffered from burnout, some people came and left within a week. They are 25 people in the team. If you are asked to give suggestion on how to improve the department, do not answer, it is a trick question, you will be reported to HR for having a negative attitude. The company is located in the middle of nowhere, if you don't have a car, it will be difficult to get to work, you can take the bus, emphasis on THE bus, there is only one which runs once an hour, if you miss it, you have to take a taxi which will cost 10 pounds. The bus is always full, be prepared to stand. You can take the job if you are desperate, my advice would be to keep looking for something else, the department will not get better as long as the managers are there.
