ROAD delays are possible on Monday and Tuesday as truck-drivers are planning blockades and go-slow protests at about 50 sites around France.
Their targets include oil refineries, factories and industrial estates - but also motorway tolls, ports and airports.
The drivers are calling for a five per cent pay rise, a minimum €10 hourly wage and a 13th month's pay at the end of each year.
Blockades will begin at 22.00 on Sunday night. It follows a similar protest before Christmas that brought disruption to Rungis, France's biggest wholesale food market.
Unions say the action will last "until at least Tuesday" - and they are calling on coach drivers and other workers in the logistics sector to join in as well.
