A small union at Paris airport operator ADP said Monday it had filed a strike warning for Friday, the day of the Olympic Games opening ceremony, rubbishing a recent deal with management, AFP reported.
Last week's accord that fended off a walkout by larger worker groups offered only "partial and modest gains", said the Force Ouvriere (FO) union, which represents almost 12 percent of ADP staff.
Citing "a feeling of discontent" among workers, it filed formal notice of a walkout from 5:00 am (0300 GMT) on Friday to 7:00 am on Saturday.
As Friday is the day of the opening ceremony, no civilian flights will be allowed from 6:30 pm to midnight in a 150-kilometre (90-mile) radius around Paris -- limiting the potential impact of the strike.
ADP was unable to comment immediately on the effect FO's strike could have.
The union is demanding an increase in a bonus agreed last week from 300 to 1,000 euros ($326 to $1,088) as well as other pay steps.
FO's strike warning comes as smaller unions representing pilots and flight attendants at carrier Air France are also stopping work this week in protest at plans to quit Orly, one of the capital's three airports.
The company "will operate its full programme of flights" despite the strike, a spokesman told AFP.
