I think this is the only place ever where people go on about getting the sack if you go on a strike. You CAN ONLY GET THE SACK IF IT IS DONE ILLEGALLY!!!! Legal industrial action is JUST THAT LEGAL!!
You could at least google it before you make yourself look stupid.

The consequences for employees of taking industrial action
Employees who take industrial action will know that there may be damaging financial consequences for them, since they are unlikely to receive any pay if they withdraw their labour. They should also be aware that they are putting their jobs at risk.
An employer may take various measures, up to and including dismissal, against any employee who takes industrial action. An employee who is dismissed by his employer while taking industrial action may lose his right to claim unfair dismissal.
