Employment Bill [Lords]

I have a lot of sympathy for my hon. Friend's new clauses, and I am inclined to vote for the one on which he will call a Division, but, on the point that he just made, I am concerned that we would be asking the employer to prove a negative—that the interest in striking was not for the reason for the proposed dismissal. I wonder whether it would not set an impossibly high hurdle, whereby someone who was threatened with dismissal could threaten to strike to invoke the new clause.
