General incompetency and laziness of the management. The large flow of money coming from membership fees is squandered and there is no responsible financial management.
I think there is not much clarity within the management and I saw terrible employee treatment. Despite being a small organisation (more or less 80 employees), they managed to fire 5 employees in 6 months. In every one of those cases no notice time was given and the reason underlying the decision was never communicated (or a clearly invented one was given). Even without counting those terminations, there is a high turnover of employees, which is symptom of something going clearly wrong. Total abuse of interim contracts and absence of transparency about the process leading to a contract. I know of someone who had been working as an interim for several months who was given the fake promise of an undetermined contract and was laid off on the spot without a single warning because they didn't have enough experience. This is unfortunately not an isolated case. Furthermore, interims have to pass a test with a so-called psychologist to get a contract. It has happened that based on a personality test the "psychologist" determined that a certain employee didn't have the personality of the role they were holding and the worst of this is that HR took this seriously and fired the person. Finally, no notice is ever given to the rest of the organisation about the fact that a certain employee doesn't work there anymore (a part from very senior employees): After someone gets fired, colleagues wonder for quite some time where that person ended up until finding out through gossip that they had been let go.
No career progression.
