In the US we have what's called at-will employment in 49 of 50 states. It means that (barring protected reasons like age/race/gender/family status) employers can terminate their employees at any time with no notice, for any reason or no reason.

"The protection goes both ways" they say, as you can leave your job and quit with no notice just the same, but it's quite an imbalance as the employee leaving does not generally have any impact on the employer's health insurance, while employees generally do depend on their employer-provided health insurance.

The person's asking about the EU, it was the UK.

Then again asking about the "EU" is a bad question as every country in the EU has wildly different laws, even now the UK has left.
