marmalade & chasm :
19 is a type of not being at work strike. Not sure how much more of a clue I can give without giving the answer!
59 is a 'container' type clue - an abbreviation for the pre-Christian era inside a word for 'vessels'.
72 - the first word is an anagram of an author's pen name, and the answer is the name of his detective character, the first word being a breed of dog.
Hope that helps!
