The Civil Service/public sector has served this country well for hundreds of years. However, there seems to be an increasing tendency for politicians to abuse or blame public servants of all kinds for governmental policy failings, financial strictures, or lack of decision making/ownership failure by ministers, usually for political purposes and they do this at their peril. You do NOT shout at or demean senior civil servants in public. They cannot answer back, this is bullying. Challenge them by all means but do this properly. These guys are hugely competent, dedicated and very bright indeed, whilst normally, very quietly, trying to protect your apolitical arse. Salaries are crap, pensions under attack, and push come to shove they can always go elsewhere to produce a better brighter soap sud, but with Jag.
