"... On the other hand, there are cases where an employee is
required to embark upon some undertaking for the purpose of
his or her work in circumstances where, notwithstanding that
it extends over a number of daily periods of actual work,
the whole period of the undertaking constitutes an overall
period or episode of work. Where, for example, as in
Danvers, an employee is required to go to a remote place and
live in accommodation provided by his or her employer for
the limited time until a particular undertaking is
completed, the correct conclusion is likely to be that the
time spent in a new locality constitutes one overall period
or episode of work rather than a series of discrete periods
or episodes of work. An injury occurring during the
interval between periods of actual work in such a case is
more readily perceived as being within the current
conception of the course of employment than an injury
occurring after ordinary working hours to an employee who
performs his or her work at a permanent location or in a
permanent locality."
