I am having a hard time trying to make this sentence grammatical, idiomatic and easily parsed; all at the same time.
The UI program provides temporary income support to eligible unemployed workers while they actively seek new employment or obtain vocational training [comma?] and to those who take time off from work due to sickness, pregnancy, childbirth, or to provide care to a critically ill child or a sick family member with a significant risk of death.
I was told to add a comma after training. Given they are not independent clauses (one subject, UI program; and one verb, provides) I don't understand why there should be a comma.
I am confused about the second part. Is the usage of "or to" correct?
"and to those who take time off from work due to sickness, pregnancy, childbirth, or to provide care..."
After trying for hours, I was suggested to use a run-in list alternative:
The UI program provides temporary income support to (1) eligible unemployed workers while they actively seek new employment or obtain vocational training; and to (2) those who take time off from work due to sickness, pregnancy, childbirth, or to provide care to a critically ill child or a sick family member with a significant risk of death.
