Leadership is not collaborative. Exec is like an exclusive club that looks down on the rest of the organisation. Plenty of examples where the performance of people has been graded by the Exec without consultation and, alarmingly for those not graded as a top performer, no evidence of a plan to improve. Lots of people end up leaving, feeling undervalued and, quite frankly, beat up by the way they have been treated.
You are not given the tools or time to perform to your best. The culture since Covid is to have your days blocked by meetings, meaning that you get roughly 5 minutes a day to actually do work.
There is a chasing culture at TU, setting unreasonable expectations to achieve goals. Most managers and exec rely on emails and escalations to get things done. Very transactional way of working and whilst leadership always imply that they are being 'strategic', the business is being held back by the culture of moving from one task to the next, and they mostly scapegoat junior members for not being able to hit strategic goals.
Finally, if you are considering TU as a place to work, please remember that TU Europe is a very different workplace to TU US (headquarters). It is a regional business that is kept in its place by US and you shouldn't expect to see the same budgets as they get.
Finally, whilst benefits are generally pretty good (PMI, Pension), salaries are out of touch with the market. I suspect most people would be offered higher salaries elsewhere.
