As a small employer that pays sick pay rather than stat sick pay - there are high risks in employing someone with a high absence rate. The impact is bigger when you have a small team.
I think stat sick pay should be replaced by a Gov back insurance scheme that all employers pay into, they would pay a percentage of their wage bill to cover when people are too ill to work. You give everyone proper sick pay whether they work for a small employer, on min wage or a big international.
In doing this employers don't directly feel the costs of high absentee rates associated with employing people with disabilities who might need more time than most others would off sick.
There is a fear that if you employ a disabled person you can never sack them - while this isn't true, it is a very tricky thing to negotiate and it certainly does not encourage employing someone with a disability.
I'd do the same thing for maternity pay - so everyone can have a reasonable amount of time off not just those who work for companies who can afford to pay for staff when they are not working.
And in doing this you give people more security and you support small businesses grow and support the economy.
