The net seems to be closing in on commuters who normally travel more than 90 minutes to work, by any mode of transport. BA may now effectively require these employees to position closer to LHR the day before a duty and stay overnight (at their own expense) to ensure they are seen to be adequately rested before report. An EASA recommendation may be implemented as a requirement.
The roster pattern, even on long haul, is trending towards only 2 days off between trips. This travel requirement could mean very few nights at home for those that live outside a normal 90 minute journey time.
Once BA management start a drive towards a goal they normally get what they want. Anyone considering joining BA should plan on a requirement to live within 90 minutes travelling time of report.
