Pros
Relaxed environment as bosses are never around; flexi-time. Benefits are 4% pension and partially paid health insurance - no other bonuses.
Cons
It's a family run business, which essentially means chronic nepotism. It also features a number of high rank individuals with no particular purpose within the company (they're old friends of the CEO), who get huge salaries for wasting office space and disrupting everybody else's work, often using bad manners and foul language. Job positions are advertised as a 37.5h/week job but they are in fact a 40+ h/week, as breaks are not paid and Friday is a full day for everyone. Plus by contract you are expected to work overtime without pay if necessary. Not a chance of career progress (or "being part of the family"), especially if you don't share their political views and religion (DUP/Creationist). Needless to say they are Euro-phobic, which is ironic given that a good part of the workforce is Eastern-European, including over half of the engineering department. Employees are essentially victims of InvestNI which - I am told - pays a generous portion of the workforce. The company therefore gets 'rewarded' for employing people, and the effect is that employees are seen as disposable. I have once heard the CEO 'complaining' that he did not know what to do with all the money he gets from InvestNI, which says it all.
