The car-rental company has provided employees with notepads on which to write their suggestions and envelopes addressed to the Avis board.
The initiative is part of Avis' drive to capture a bigger slice of the car-rental sector, with a focus on online rentals. In 2004 online reservations accounted for 24% of the company's bookings.
The ads, due to break in May, will be the first since Avis hired Ogilvy & Mather in February. The activity, which will comprise print, online and direct, will use the tagline 'We try harder'.
