No, actually the sick calls are real. The complicating factors are a) it’s summer, so staff who would normally be available to backfill a sudden absence aren’t available b) a Covid absence is not a 24-hour flu…. once the person gets sick they stay off longer, so the impact of any one absence is greater and c) there is a staff shortage, so again no defense in depth.
Doubtless you're entirely accurate; but there's no excuse for GO or Alstom.
Self-inflicted wounds are real, but not reasonable.
Covid has been a known commodity for ~ 2 years now; and summers happen every year.
There should be sufficient staff hired, trained, retained to operate service with spare board, in all seasons.
If one is responsibly doing all of the above, that minimizes any risks.
Add to that,if one is tracking that planning is delivering results (in this case in staffing) as it should; and sees any indication of a problem, you start doing what you need to by way of mitigation, early.
- Accelerate burn-in of new staff; up retention bonuses, ask nicely for people to defer some vacation time, and compensate them accordingly.
