BA cabin crew have voted in favour of strike action. At present they are not setting any dates for the strikes but you can be sure they will aim to cause maximum disruption so I would think it will include the Easter period.
I don’t know about you but my holidays are precious to me and I do not feel very much in favour of having my annual leave being mucked up by strike action. No doubt the cabin crew have some grievance but the people they are upsetting are the general public who on the whole, I would imagine, would not be behind them nor think favourably of them for ruining their few days away.
There was a time when trade unions were a necessity to help the everyday worker but nowadays the vast majority of people work for companies where they have no unions to fight for them and the holidays that they have are sacred to them.
