Aer Lingus cabin crew member Anne Gillespie was pictured in several national newspapers taking her young child in a buggy during the action at Dublin Airport.
Ms Gillespie was part of more than 300 crew who walked to the airline’s head office where a letter was handed in to the airline’s chief executive, Christopher Mueller, on behalf of staff.
Staff are furious after new working rosters were introduced across the board at the company.
The airline has sent more than 140 letters to cabin crew warning them that those who refuse to co-operate will be sacked.
In the letter to management Aer Lingus staff said they were loyal to the company but were also loyal to their families.
They say the new working rosters will simply make it impossible to have a normal family life.
