Against a background of high staff turnover and unrealistic company targets, staff - particularly junior staff - are encouraged to work long hours and to make the business and the work a core part of their lives, for no additional reward or acknowledgement. Those who manage to pull through end up digging their own graves - "exceptional" overwork becomes the rule due to the founders' inability to see that this is not a sustainable way to run a business.
Numerous talented and capable "buffers" were hired in recent years to try to mitigate the operational and managerial failings of the founders, but they were driven or pushed away when it became clear that they were undermined or otherwise not empowered to make the necessary changes.
Extensive lip service is paid to wellbeing, inclusion, and even work-life balance, but this flies out of the window at the first sign of stress or pressure: instead, these platitudes become another tool with which the founders can gaslight the employees into believing that staff wellbeing is in any way a priority. Similarly, the company "values" are used as bludgeons for getting the founders' way in almost the same breath that they are used as examples of a positive culture. Name a toxic startup trope - you will find it alive and well here.
