The DTC union says the drivers’ demands are not unreasonable and the protest will continue until they are met.
Union president Lalit Chaudhary made the statement as the strike continued.
The government says some benefits have been approved.
The union wants a daily wage of Rs 2,000.
Thousands of buses remain off the roads.
Transport Minister Pankaj Singh said the administration had already approved certain benefits, including medical facilities, leave compensation, additional kilometre payments and death assistance.
The government distinguished between direct DTC employees and those hired through private contractors.
Union president Lalit Chaudhary said the drivers were not asking for anything unreasonable and that the protest would continue until the demands were met.
Reports differed on the day count, with one report calling Friday the fourth day of the strike and another saying it entered its fifth day on Saturday.
No emergency order to end the strike was reported in the accounts reviewed.
The strike began earlier in the week and continued through the weekend.
Many Delhi residents rely on DTC buses for daily commuting, so even a short strike has a wide impact on the city.
The strike by contractual drivers and conductors of the Delhi Transport Corporation continued through the weekend of September 19 and 20.
It is led by the DTC Karmachari Ekta Union, which claims that more than 10,000 drivers and conductors are taking part.
The union is demanding a daily wage of Rs 2,000, against the current Rs 862 a day.
Other demands include medical facilities, social-security benefits, an annual bonus, payment for government holidays and leave.
Thousands of buses remained parked at depots across the capital.
Services were reported to be hit in areas including Burari, Wazirpur, Nehru Place, Rajghat, Rani Khera, Ghumanhera and Sarita Vihar.
Long queues were seen at bus stops, and some e-rickshaw drivers were asking Rs 15 to Rs 20 for distances of two to two and a half kilometres.
