It was revealed last week that a further 16 staff at the authority are also facing the sack within the next few days after the sneak thieves were caught out by a secret video camera.
One senior council insider said: 'It is very likely that these 16 will be leaving the council quite soon to avoid further embarrassment.'
The camera was hidden inside a smoke detector next to petrol pumps at a council depot which is used for refuelling by council vehicles. Some drivers were taking up to 20 gallons of diesel a week for their own private car use.
A spokesman said that the council is conducting interviews with a number of employees, the results of which will lead to disciplinary procedures.
Meanwhile, a team of 14 council workers has been suspended over allegations concerning overtime. The matter came to light after bosses found they had been the only men claiming to be at work during a weekend of horrendous weather when no one else could turn out.
A spokesman for West Lothian Council said: 'An investigation is being conducted within the building maintenance section. It concerns overtime payments. The men have been suspended on full pay.'
