Over 30 security workers with Group 4 Securicor stopped work on Tuesday and blocked Guernsey airport's departure lounge until bosses signed a recognition agreement with the T&G.
Airlines Flybe and Aurigny were affected by the disruption as flights were grounded for an hour.
Thisisguernsey.com reported on the anger of airport bosses that the surprise action provoked, although for the workers the action rapidly achieved its goals.
Their article stated: AIRPORT security staff who went on strike yesterday have been accused of holding passengers to ransom.
