More than one subject
We usually use a plural verb:

But if we see the items as a single entity, we use a singular verb:

Health and Safety has to be a priority.
'One of'
'One of' is followed by a plural noun but does not take a plural verb because it refers to 'one of a pair or group':
One of my colleagues is sick. 
One of my colleagues are sick.
