If you terminate him before the 6 months is up he cannot make a claim for unfair dismissal
Here is some information.
If he cannot fulfil the criteria of the job then you also have an alternative to change him from full time to part time.
You have to be careful not to terminate him because of illness. So you do not have to give him a reason.
I hope this makes sense and is of assistance. If there is nothing further
