Are you still blaming the managers that left eight years ago?
Whilst I agree with what you are saying, you also have the other side trying to whitwash 13 years of labour as though the country resets every election.
Thatcher left a bad legacy in some areas, so did Blair/Brown, you cannot just wipe it off as "not true labour" and think that some of the issues today are not routed in a lot of New Labours policies.
At the time ATOS was rightly derided, but for some, benefit restrictions started in 2010 and is the second coming of the Third Reich. Low wage, zero hour contracts can be traced back to Labour, the Global Financial crash wasn't caused by labour, but we were just as culpable in sub prime mortgages and it doesn't matter that a lot of Tories backed the idea, Labour was at the helm when more bank regulation came through.
If some blame previous managers, others refuse to accept any wrong doing as to why they were sacked.
