Alleging partiality in extending work permit for tour vehicle operators inside the Arignar Anna Zoological Park, Vandalur, workers and staff staged a protest in front of the Zoo Director’s office on Thursday.
More than 150 tourist drivers, including selection grade and special grade staff, are working in the zoo for more than 25 years.
“We have been asked to submit our documents before Wednesday,” said Iraniyappan, secretary, AAZP Staff and Workers Union.
The union was demanding extension of their work permit and upgradation of animal maintenance as well.
The protesting workers sought an appointment with Zoo Director, KSSVP Reddy, who will be retiring on July 31.
Mr. Iraniyappan said they would be forced to intensify their stir if they are not given an appointment.
The Zoo Director could not be reached.
