Whether or not you're a train passenger, you can't have missed the numerous strikes which have disrupted the UK's railways this summer. And they're not over yet.
Unions including the RMT and Aslef will be taking more industrial action later this month. Aside from transport, there are also upcoming strikes involving bus drivers, port workers and barristers.
"Industrial action is 'official' if it is formally backed by a trade union and members of that union are taking part in it," NI Direct explains.
