Trending @Accenture; Full time presence in office in A B C shifts?

So I was recently transferred to a support project abruptly. This is a 24x7 production support project. It has 3 shifts - 6-3, 2-11, 10-7.

On the days I am supposed to work from office, am I supposed to spend the whole time in office? All the shifts have non-general timings. Staying alone in a city with these commute hours seems difficult.
