No honest transparency of current company status to the employees. this manifests as sudden large scale decisions that could not have been anticipated and were even anticipated not to happend directly by management. for example, there were massive layoffs during COVID-19 after for a several months the management stressed out that this is not anticipated in the short term. a very very short time after the layoffs of really great professionals and people the company began rehiring for the same exact positions, which raised some concerns among employees regarding the management's integrity and honesty. The company does not behave as one cohesive unit and feels like different divisions are way out of sync with mission statement, KPIs and targets. No innovation efforts effectively occur, and the company ends up being very old fashioned, slow paced and all other bad aspects of a large corporate vs a startup - the problem with that is that there is a dissonance between the company being a startup and it's corporate-ish state of being - ending up suffering from the worst of both worlds :
Corporate slow pace and bureaucracy overhead and lack of professionalism of a small startup. also salaries are not on par with startup market. the company also repeatedly failed to preserve talent, losing many great people to other companies where they felt like they had a much richer and viable growth path.
