SPARKS celebrating the reinstatement of a sacked colleague will be back “in greater numbers” unless they secure “full capitulation,” they warned yesterday.

Electrician Graeme Boxall, previously known as Graeme Smith, was dismissed half an hour after being elected a union rep last Friday. But he was offered his job back yesterday — pending gardening leave — after an early morning demo outside the building where he had been working.

Police threatened to arrest pickets outside investment bank Morgan Stanley yesterday and angry managers waved paperwork in workers’ faces saying they had secured a High Court injunction banning the protest. Sparks shouted back: “So what?”

Mr Boxall was employed by sub-contractor D&D for electrical work at the bank.

But under collective bargaining agreements signed by Phoenix, the company commissioned to carry out the work, bosses are supposed to oblige workers’ requests for direct employment. Instead, the Unite activist was shown his P45.

Mr Boxall told the Star he was “happy” with the result and “honoured and awestruck” by support from Teesside and Liverpool-based workers who travelled down for the demo, along with workers on the job who refused to cross the lines.

As the Star revealed yesterday, D&D director Danny Green cried down the phone at Mr Boxall from his holiday over the weekend, fearing he could lose his contract over the row.

“We wanted full capitulation and compliance with the Joint Industry Board conditions,” Mr Boxall said. “Failure to do so on [D&D director] Danny Green’s return will mean we’ll be back [picketing Morgan Stanley] and back in greater numbers.”

Mr Green is reportedly sunning himself on an exotic cruise after getting married this weekend. Workers say they have been told he cannot be contacted due to poor mobile reception at sea. He is due to return on August 12.

Mr Boxall said he planned to travel to Redcar during his gardening leave to thank local workers for their support.

Workers have held weekly unofficial pickets at the gates of a new incinerator, where foreign firms have been employed to undercut collective bargaining agreements.

“When people are prepared to lose money to act in solidarity with you, there’s always an onus to return that,” he said.
