I worked at Tishcon Corporation's QC Chemistry Lab for just under a year and it was an extremely rewarding position.
I will spare you the trouble and jump into the hardest part of the job first. Due to the nature of QC chemistry and because you are doing quality control for a manufacturing plant, you are expected to jump right into the work pretty quickly and complete the chemical analyses by certain deadlines. However, after your first few months the workload becomes very manageable as you gain experience. While chemists are typically assigned to a specific instrument or set of techniques, work is differed as needed.
Management is very accommodating with vacation time, sick time, and they are very good at their jobs. I only have good things to say about management and it is likely that you will as well. My favorite part about management is while they have doctorates, certifications, and a wealth of experience they are also very humble/easy to talk to.
My co-workers all come from different backgrounds and it is interesting to have such diverse peers. Everyone tends to mind their own business when they have a lot of work to do; however, everyone is very sociable and friendly.
I highly recommend Tishcon Corporation for those who enjoy a challenging career, possess a desire for self growth, and do not mind a slightly lower salary.
I only have one suggestion for management. You should pay your chemistry laboratory employees a higher base salary. You will find motivated chemists who are willing to stay with you for the long term. There are many great opportunities that I have found here and haven't been able to find anywhere else.
