Worked for this company for 8 years and was a model employee. I rose through the ranks and was well respected my everyone in the company, except one manager, Jill (won't disclose last name so as not to be seen as slandering directly). Jill found it within her power to immediately release from my position one random day due to a false claim that had no merit and no credibility. Just a vendetta from a person in power who did not appreciate someone who spoke their mind and challenged the status quo. Never work for this company if you have any integrity.
