Strikers hoping to bring chaos to the transport system have completely failed, say heads of Isle of Wight business.
London Underground workers walked out in two waves at 5pm and 9pm on Monday in a row over job cuts. The strike is the first in a series of threatened stoppages.
Unions said support for the action was "rock solid".
But their efforts to bring business to a standstill are not working, according to Colin Plastic, chairman of the island's Chamber of Commerce.
He said; "I've been in constant touch with members throughout the island today, and they all confirm that everyone has turned up for work as normal.
"We were fully prepared with fleets of extra buses and cars around the island but the tube strike is not causing our people any inconvenience whatsoever.
"This is just further proof that Isle of Wighters are a determined lot! Well done to everyone!"
