Johannesburg - SANParks will postpone bookings for 2018 for at least one week in case employees continue their strike, a spokesperson said on Monday."It is just a precaution in case the strike continues. The call centres will be overloaded," Janine Raftopoulos said.Bookings for 2018 were supposed to open on July 25, but would now open on August 1.SANParks manages the country's 19 national parks, which include the Kruger National Park, Table Mountain National Park and the Karoo National Park.Last week, the Health and Other Services Personnel Trade Union of South Africa (Hospersa) declared a nationwide strike at all SANParks facilities. It, however, suspended the strike over the weekend.Whether or not the strike continued would depend on the outcome of a meeting scheduled for 14:00 on Monday."We will see if the negotiations are meeting our demands," Hospersa spokesperson Kevin Halama said.Hospersa-affiliated employees want a 9% wage increase for 2018, while SANParks is offering 6%.
