Multiple associations

hi everyone,

i have just started learning UML and currently, im applying it to one of my projects. a problem occured when multiple association of a class to another was present. eg. i have a class HRManager that derives from Employee. besides that, the HR manager is also responsible for the Employee’s addition, update, schedules, leaves, and more. How do i transform this into a digram? having too many connecting lines for every association seems quite wrong (i think).

One other thing: for example you have classes Schedule, Benefits, Deductions. this classes do not have a logical grouping (eg. trainagle and circle are shapes), but those three all possess similar properties: ID, Name, Description and others? How do i group them or should i even group them? help!
