SECURITY workers at two of Scotland’s busiest airports will vote on strike action after rejecting a “miserable” pay offer.

ICTS Central Search employ more than 300 workers — 220 at Glasgow and another 100 at Aberdeen — in passenger searches and mobile security patrols at the airports.

But staff have become increasingly concerned that understaffing and workers’ fatigue could put passenger safety at risk ahead of the summer rush.

Just one week after their union, Unite, warned of the dangers of understaffing, workers have rejected a pay offer — amounting to a £500 one-off payment and 4 per cent backdated to January — from the company which has seen its profits soar by almost 40 per cent to £3.2m over the last year.

Unite general secretary Sharon Graham said: “Workers at Aberdeen and Glasgow airports have emphatically rejected ICTS’s miserable pay offer.

“The company is extremely profitable and it can easily afford to make a far better offer to our members.

“Unite will fully back our ICTS Central Search members in their fight for better jobs, pay and conditions.”

ICTS Central Search and airport owners, AGS Airports, were approached for comment.
