I paid sentries for working -- people getting regular payments (13)

I believe the answer is:

stipendiaries

Here is my best explanation:

'people getting regular payments' is the definition.

'i paid sentries for working' is the wordplay.
'for working' indicates anagramming the letters.
'i'+'paid'+'sentries'='ipaidsentries'
'ipaidsentries' is an anagram of 'STIPENDIARIES'.
