It certainly is in Scotland, where coach Andy Robinson has clung on to his post by his finger nails. Mind you, the Scottish Rugby Union did not force the issue, even after their Six Nations whitewash earlier this year, because Robinson is said to be on a £300,000 (almost $600,000) annual contract which still has a couple of years to run.
But a bad defeat to the Wallabies on their June tour could force Robinson to walk. He almost did back in March - significant signs of real progress on their tour this month will be needed to stay the growing criticisms back home. You never know, and Edinburgh did do very well in the Heineken Cup, reaching the semifinal. But as in the case of Leinster, what happens at provincial level can mean nothing when it comes to international rugby.
England, meanwhile, had a surprisingly good Six Nations, losing only to Wales. Victories over France and Ireland persuaded the RFU to give interim coach Stuart Lancaster the job fulltime, ahead of Nick Mallett. But now comes the real test of Lancaster and his men; a three test series against the Springboks in South Africa.
England's problem is that ex-All Blacks coach Wayne Smith turned them down for the post of backs coach. That has left a major hole in the England coaching team for Smith would have brought so much with his quality and reputation.
Only Wales have a national coach who is not under microscopic examination. In Warren Gatland's case, it is just his ankles that are suffering that sort of scrutiny after his calamitous accident at home in New Zealand. Robert Howley takes charge for the tour to Australia, but the pressure is off Wales after their commendable World Cup campaign followed by that Six Nations Grand Slam. They have a largely young, exciting squad and could give Australia some serious problems. It is within their reach to win one of the tests.
That leaves France but after a shocking Six Nations and long, long season they're again in disarray. They're not even thinking about their trip to Argentina yet - this weekend sees the semifinals of the French Championship with the final next weekend. In French eyes, that is called getting your priorities right.
