The rising cost of fuel in Barbados has prompted the National Union of Public Workers (NUPW) to call for a hike in allowances for public servants.Noting that allowances have not moved in over a decade, the union’s general secretary Richard Green and president Kimberly Agard argued that with gas prices here being among the highest in the world, it was necessary for travel benefits to be adjusted upwards.Their call came on the heels of another price hike that took effect on Sunday which saw the cost of gasoline rising to $4.83 per litre, an increase of 11 cents, and diesel increasing to $4.28 per litre, an increase of 20 cents.“Because of the significant rise in the cost of petroleum, the current rates for travel allowances is really out of sync with the cost of gasoline now, and those rates are in excess of 10 years old and in no way bear any relation to the cost of gasoline now,” Green told Barbados TODAY.
