Royal Mail shares, which have fallen 16.3 percent this year, were up 0.3 percent at 386.8 pence at 1521 GMT. But the workers are determined to keep fighting-and say bosses' action has only strengthened their resolve.
Royal Mail has halted Britain's first planned national walkout by postal workers since it was privatised, after successfully applying for a high court injunction.
Royal Mail says the CWU is in breach of its contractual obligation not to call for strike action until the external mediation process, which began on October 5, is exhausted.
When CWU did not call it off, Royal Mail lodged an injunction with the High Court, which was heard this morning. "We must work together to save it", he said.
Royal Mail responded to the announcement by calling the action "illegal".
David Jinks, the head of consumer research from rival parcel firm ParcelHero, said: "If industrial action goes into the seasonal period it will have a huge impact".
Juan Martin del Potro battles past Alexander Zverev at Shanghai Masters
Zverev has already joined Federer and Shanghai top seed Rafael Nadal in the field for next month's ATP Finals in London. And then came the turning point as he yielded the crucial service break to go 3-2 down in the third set.
The CWU has accused Royal Mail of carrying out a "relentless" programme of cost-cutting to maximise short-term profits and shareholder returns.
The court's final injunction means that any strike action before the dispute resolution procedures have been followed would be unlawful.
The vote was the first under the Government's controversial Trade Union Act, which was passed earlier this year and requires strike ballots to have a 50 per cent turnout - 73 per cent of the CWU's 110,000 members voted.
CWU Deputy General Secretary Terry Pullinger had previously refused to reveal whether a strike could hit the Christmas post when the ballot result was announced. "We're going in there with a 90% vote for action and whatever happens today we'll be walking out of here with a 90% vote for action". And we've walked out of court with a 90 percent yes vote intact.

But at the very least the result shouldn't be allowed to demoralise postal workers.
