Meaningless for tech workers in the UK. You quit from a £100k a year job, your £90 a week isn't going to be noticable.
Far more useful is if your employer lays you off (short of major disciplinary reasons), you get at least 1 weeks pay for every year you've worked there (1.5 weeks if you are older).
In the US when you quit it's $0.00. In other countries it's the same benefit as if you had been laid off. We probably agree the latter is the best policy. I'm just saying, other countries have done it. We don't have to guess what the results would be.
Including taking classes in your desired field IMO, not just being actively engaged in two hiring processes at least once a week (which is what my state mandates for UEI).
This actively looking for one is normally implemented by showing a job search log. It is however especially with indeed and LinkedIn to fulfill this requirement in 15 minutes per week if you really wanted to without any intention on working.
For those that DO want to work this means that employers are looking at piles of fake applications from people that don't want to work and an increased chance of being filtered out.
