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.
"If you're involved in industrial action against your employer, you'll probably be in breach of your employment contract and you are therefore unlikely to be paid when taking industrial action. However, you will be protected against being dismissed for taking industrial action provided your union follows the right procedure when organising it."
