What are you talking about? The US doesn't give carte blanche either. Discrimination law exists. Other labor laws exist. Exactly as this article refers to as being 'not carte blanche' in the UK. 'At will' in the US and the 2 year qualifying period in the UK are practically identical, apart from that the UK has a 2-week statutory notice period. The protections that remain in both the US and UK are almost entirely about protected classes. Even the classes themselves are virtually the same. "Have they been there less than 2 years?" is the first thing legal will ask you when you want to sack someone in the UK. It's a wholly different status to being protected after the period.
