Company carpark labels are often colour-coded to differentiate directors from managers, managers from executives, and executives from non-executives.
The “biggest” label, likely to be black to match the many dark-coloured Mercs and BMWs popular with top brass, entitles the holder to a reserved, sheltered parking space right in front of the main lobby, complete with a little red carpet. Closed-circuit television and a sentry with his eyes half-closed protect the boss’s expensive ride.
Managers with their grey carpark labels get to park their cars in proper lots beside the building, but in the open, with token shade from nearby trees and a few potted plants. Security is provided in the form of a signboard threatening to wheel-clamp unauthorised vehicles, which would include the humble runabouts driven by executives, who are supposed to park on the grass at the other end of the premises, as indicated by their grass-green carpark labels.
Said labels have designer white dots on them, to signify the daily bird-dropping bombardment that the poor execs can expect at their authorised corner of the company carpark.
As for junior workers motoring on a shoestring, they get a red carpark label that matches the “in the red” financial situation they’re in because of the budget rides that busted their budget. The designated parking area for red-labelled jalopies is usually between the busy loading bay and the smelly rubbish compound.
