i find that 981 route plies similar to part of 856 route.maybe can consider extend 981 route.how you find it?(maybe extend to woodlands bus regional interchange and made it a whole day service . )
from what i feel lah:
981 go deep into the senoko right, 856 does not. and the demand dep into senoko is only during kocking off or time to go work hours right?
so shd be justified o have this workers service 981 so that workers there no need walk like hell to 856 bus stops.
something like the SBS68 or SBS37 lah. 9excpet 37 is sort of whole day)

Sv. 981 only has demand during peak hours, when workers go to work and knock off. It would not be feasible for it to be a whole day service as it's not profitable!
