Does getting Job insurance make sense?

I work in product for a series A funded startup that just laid off 40% folks in my team.

Work environment has become tremendously stressful with top management continuously threatening about every small thing.

Although getting job insurance seems like a good idea - still not completely convinced these are reliable

I have been applying for a jobs since past 4 months but with no luck - tha market seems too saturated at the moment

Anyone here got reviews or first hand experience of the same, please pitch in :)
