And this fuller story, a few days later, including -
" ... Larkin, disguised as an old man, with a false beard and decrepit gait, watched the detectives searching the hotel where he was staying. He subsequently addressed a meeting from the hotel balcony, and was recognised by the crowd. He submitted quietly to the police."

Perhaps the article has confused two separate occasions. Larkin's Wikipedia article says ...
" ... Larkin and others were arrested for sedition on 28 August, and he was released on bail later that day. Connolly told the authorities "I do not recognise the English government in Ireland at all. I do not even recognise the King except when I am compelled to do so."[22] On 30 August, a warrant for Larkin's arrest was put out, claiming he had again been seditious and had incited people to riot and to pillage shops. When a meeting called by Larkin for Sunday 31 August 1913 was proscribed, Constance Markievicz and her husband Casimir disguised Larkin in Casimir's frock coat and trousers and stage makeup and beard, and Nellie Gifford, who was unknown to the police, led him into William Martin Murphy's Imperial Hotel, pretending to be her stooped, deaf old clergyman uncle (to disguise his instantly recognisable Liverpool accent). Larkin tore off his beard inside the hotel and raced to a balcony, where he shouted his speech to the crowd below. The police – some 300 Royal Irish Constabulary reinforcing Dublin Metropolitan Police – savagely baton-charged the crowd, injuring between 400 and 600 people. MP Handel Booth, who was present, said that the police "behaved like men possessed. They drove the crowd into the side streets to meet other batches of the government's minions, wildly striking with their truncheons at everyone within reach ... The few roughs got away first, most respectable people left their hats and crawled away with bleeding heads. Kicking victims when prostrate was a settled part of the police programme." Larkin went into hiding, charged with incitement to breach the peace. Larkin was later re-arrested, charged with sedition and was handed a 7-month imprisonment. ...

Or is this photo of his arrest on Sunday 31 August in the Imperial Hotel disguised as an old man?

...most of the men are wearing shirts and ties, does this indicate that it might be a group of more "white collar" workers ? it's before the time of three word protest slogans

Portadown News - Saturday 29 November 1913 quoted the slogan in the picture in connection with Jim Larkin on his release from prison in 1913. It was already a "well-worn" phrase then.

Mr Larkin, when he left Dublin after being released from prison, said he was going to raise the fiery cross and rally workers in other parts of the kingdom to the support of the Dublin strikers. The manifesto which he has addressed to the British workers is his fiery cross. It remains to be seen what response will be made to it. Mr. Larkin seems to be rather doubtful about the leaders at any rate, and makes his appeal to the rank and file. He says the leaders have come short of the gospel of human brotherhood, which is the spirit of trade unionism, and is embodied in "a well-worn phrase, 'An injury to the one is the concern of all.'" He claims on behalf of the workers generally "that you meant and still mean to put your whole body and soul into this fight in Dublin, and if your leaders have not, up to now, realised the vital issue at stake, you, O men of toil, do understand, and understanding are prepared to act."
