The Unite national officer Oliver Richardson had this to say:
In the light of this overwhelming mandate for action, Swissport has requested talks which we are happy to attend so we can try to resolve this matter.
The dispute centres on the company's decision to freeze workers pay for 18 months, from April 2012 through to October 2013, followed by a below inflation increase of just 2.5%.
Our members are struggling to keep up with the rising cost of living and Unite believes Swissport is failing to recognise the contribution its staff are making to the success of the company."
