Her responsibilities include assisting other tasks as required / assisting with other tasks as required
Which one is correct?
... assisting with ...
You can assist (help) people, but cannot assist (help) things.
Both variants are grammatically correct, but there is a slight difference in connotation.
The first variant, "Her responsibilities include assisting other tasks as required," implies that this person's primary responsibilities involve assisting with other tasks when needed. In other words, assisting with other tasks is one of her main duties.
The second variant, "Her responsibilities include assisting with other tasks as required," suggests that she has a set of responsibilities, and in addition to those responsibilities, she is also expected to assist with other tasks when necessary. These additional tasks might not be part of her main duties, but she is still expected to help out as needed.
Overall, the choice between the two variants depends on the specific context and the intention of the sentence.
