The reality is a bit more nuanced than that.
The main benefits: Jobseekers Allowance, Employment Support Allowance (ESA), (which replaced Incapacity Benefit) is now claimed under the umbrella of Universal Credit (UC). ESA claimants are put into different ‘groups’: those who are assessed as being incapable of actively seeking work and those who are able to actively pursue work.
From memory, around ⅓ of all UC claimants are in employment already but claim UC to top up their wages because they in ‘in work poverty’. What was the Tories’ answer to this? “They should just get better paid jobs”.
If you meet the criteria of the assessment, you might be able to claim Personal Independence Payment (PIP) which is payed to those in employment and those incapable of work.
