Ah, the perpetual question about group nouns and verb agreement. Which in this case is actually a question about (assumed) words.
Here is an interesting discussion, including differences between British English and American usage: https://blog.oxforddictionaries.com/2011/09/05/agreement-over-collective-nouns/
My answer (from an American English journalist, copy editor and technical writer):
"Staff" is a singular collective noun, so strictly speaking, you would write, "the staff is a group of talented people" or "The staff was broken by Gandalf" (kidding!)
However...
The sentence is referring to specific staff members -- individuals -- who are to be listed. A word ("members") is being left out of the sentence, and it clearly refers to more than one thing. In this case, it is acceptable to use the plural verb form:
"The following staff are absent today: Bob, June, Eric, Mary...."
To be absolutely clear, add the omitted word, or use a plural word instead of just "staff":
-- employees
-- staff members
-- individuals
-- people
-- colleagues
