Police were called to a City Quay office after it was occupied by protesters.
The Learndirect office in City Quay was stormed by members of the Scottish Unemployed Workers’ Network.
They took the action to voice their opposition to mandatory work placements for the unemployed, which spokesman Tony Cox described as “state sponsored slavery.”
He said: “Some people are working 40 hours a week for zero.
“If they don’t comply they risk having their benefits cut off.”
Around 12 people were involved in the protest and after occupying the office for a while they continued their action outside with banners.
Mr Cox said: “We are not against people getting work experience but if it is work experience it should be paid.
“If they are not going to pay people it should be voluntary.
“Our experience is that very many of the people who are involved are receiving no training whatsoever.
“It’s about stacking shelves and doing skivvy work in shops.
“We want real training not state enforced slavery.”
Police were called shortly after 11.30am and the protesters were search amid accusations of a missing note.
Welfare rights activists Tony Cox was previously cleared of threatening and abusive behaviour at Arbroath Jobcentre in January.
During the trial at Forfar Sheriff Court the charge was dropped by the Crown.
Mr Cox was instead fined £200 for failing to give his name and address to police officers and of obstructing them in their duties.
He maintains he should have never been asked because he had not committed a crime.
A spokeswoman for Police Scotland’s Tayside Division confirmed officers had attended the incident.
She said: “Police Scotland attended at City Quay following a protest, it passed without incident.”
