Brit's are only happy when there's something to moan about.
There are structural problems in UK Enterprise and some poor decisions have been taken under the current regime. However, it's better led now than it was under the previous management.
Some of the key issues have been; too many transactional AMs that have failed to build pipeline(and a couple of even worse RSMs); too many idle threats to those same AMs that were never followed through; some poor promotion a focus on young (untested) SEs that spend more time training than they do in front of customers (although there are a couple of diamonds in there, if they can be retained); a lack of clear career progression for either AMs or SEs (but that's true of UKI in general); SEs that chased the money to be AMs and (being charitable) are still finding their feet in the role; good SEs leaving for better pay/promotion prospects; I could go on.
Some (actually a lot, in my opinion) of the fault is not with Enterprise management, it's with the way that UKI has been run for the last few years especially with certain people more focussed on their 'extra-curricular' roles than that of running UKI.
The problems aren't all internal though, the market has shifted away from Cisco, key accounts stopped spending; the Brexit decision and subsequent impact on the £/$ rate caused a number of deals to be dropped or postponed at the end of the last FY.
Equally, the problems are not unique to U.K. Enterprise, they apply across the Board in UKI and several other EMEAR countries.
But, there's clearly a lot of bitterness and disaffection in the UKI workforce right now and I'm not seeing anyone with the ability, or resources, to fix it.
