Working at Charles River has a lot of benefits, but a lot of it drawbacks as well. I can say that the culture is great and the people are very nice, but the job is very repetitive and sometimes boring. The pay is descent, but there is no incentive to get more income. A typical day at work for a site clerk includes doing a lot of boring Standard Operating Procedures (SOP's), cleaning rooms, and a lot of other boring stuff. I would suggest working for a company that better values their employees and the hard work they put in.
No clocking in/out, hour lunch, working with animals.
No flexibility in scheduling, long hours, repetitive, and boring.
