Dundee Airport will close for 48 hours from 12pm on Tuesday due to industrial action.
The dispute involves security staff employed by AMSL – a company which merged with Highland and Islands Airports (HIAL) – who are demanding equal pay, holidays and sick pay to fellow staff.
Today, the Prospect union and HIAL chiefs were in talks to prevent any strike action.
Following the talks HIAL released a statement saying that “some progress” had been made but Dundee Airport was to close on Tuesday.
The statement read: “Following detailed discussions with Prospect, we believe we have made some progress with the union, with both sides showing willingness to compromise.
“We now require some time, with our Transport Scotland colleagues, to consider the issues we have discussed with Prospect.”
The statement also said that union members had been asked to postpone the strike, but that had been refused.
“As a sign of goodwill, we requested that the union postpone industrial action until we are in a position to reply to them in detail.
“Unfortunately, the union has insisted on an immediate response to their requests and we are simply not able to provide this. As a result, the union has confirmed that it will proceed as planned with its strike threat.
“We regret that, having come this far and made reasonable progress in our discussions, the union has presented an entirely arbitrary and unreasonable deadline, to which we simply cannot accede.”
Following a ballot from union members, 87% voted in favour of the strike.
Alan Denney, of Prospect said: “Despite attempts to find a settlement to the dispute in AMSL, the inability of the company or the Scottish government to find a way to settle this matter means that industrial action is inevitable.”
Dundee is the only one of HIAL’s 11 airports to close due to industrial action.
