Business Outlook

Pros

Pay is decent along with the benefits package offered Most people are helpful & nice to work with.

Cons

- No communication or inclusion on new initiatives/projects.

Everything is done without a structure in place. -Treatment of employees is abysmal - 1990's toxic work and blame culture =Leaving employees are not replaced, but same level of work is expected.
