I wish this somewhat flippant reference to the human rights legal bid re loss of staff travel would stop being perpetuated.
The only thing flippant about this matter is Unite's abuse of human rights legislation in this way.
If it goes unchallenged, or is confirmed as acceptable, any employer can then act against any strikers in a similar way in the future, however genuine their employees grievance may be.
Employers already can and do withdraw perks, for a variety of reasons. There's no chance of the staff travel issue ever going as far as a binding legal precedent. And if it did, all that would happen is that employers would tighten up the entitlement wording to ensure they didn't get caught out in a similar way.
