Is this strike about the ticket offices [...]

I think so - it's the last date of the originally announced series of
(roughly) monthly strike. Hence my question as to whether any further
dates have been announced, since this dispute is clearly still
ongoing.

Or do they have to have another ballot before they can proceed with
further strikes?
