The three people on board the helicopter and seven people in the Clutha pub died after the aircraft crashed into the Glasgow bar on November 29.
The Scottish Trades Union Congress (STUC) has set up a helpline to allow union members and their families who have been involved in the disaster to access free legal advice and representation.
It said lawyers employed by trade unions are experts in dealing with the legal implications of accidents such as the Clutha crash and deduct no fee from any compensation.
STUC general secretary Grahame Smith said "The thoughts of the STUC are very much with the families of those who have lost loved ones and the many injured as a result of this awful accident.
"We are launching this helpline to ensure that trade union members and their families who have been involved in the Clutha tragedy can access free expert legal support that's provided through their union.
"Many trade union members may believe that their union's legal services will only help them with problems at work but most provide non-work-related legal support. It's also very important to remember that union lawyers do not deduct any fee for their work."
Nine funerals have been held for those who died.
Helicopter pilot David Traill, 51, was remembered in a service at Glasgow University on December 7, and hundreds of police officers attended funerals last week for Pc Tony Collins, 43, on the Isle of Arran, and Pc Kirsty Nelis, 36, in Glasgow.
Funerals have also been held for the six people who died inside the pub, where live music was being played.
They were Robert Jenkins, 61, Mark O'Prey, 44, Colin Gibson, 33, John McGarrigle, 57, Gary Arthur, 48, and Samuel McGhee, 56.
A 10th person died last week after almost two weeks in hospital.
Joe Cusker, 59, from Cambuslang, died on Thursday at Glasgow Royal Infirmary.
It has not yet been established what caused the helicopter to fall from the sky, although investigators say initial evidence rules out engine or gearbox failure.
Last week Bond Air Services temporarily suspended flights of the model of helicopter that crashed on the pub after a defect was discovered on a recent flight while safety checks were carried out.
