    I have been working at Gemological Institute of America full-time (More than 5 years)


    Nobody really bothers you as long as you do your job
    Rolling over your vacation days annually
    Most of the people there are really friendly


    Pay can be better. They recently made a salary adjustment but it is still somewhat low. The salary difference between entry level and second level is big.
    Management is inconsistent and not dependable. They constantly send mixes messages in regards to expectations. It's clear that there is an extreme lack of communication within as well as between departments. While most people are friendly, there are many questionable colleagues.

    Advice to Management

    Please listen to your staff more. Be more considerate and flexible. Hire hard working and smart people, don't only looks for production robots.
