As bad as it seems, it could be worse.
My Wife’s Tosspot Rota Coordinator has a much more laissez faire attitude to it.
People go off sick (long term stress being an all too common damning indictment of the state of affairs) or leave and can’t be replaced (another, it’s seen a very good job in her ‘industry’ and there’s usually a long list of people who’ve applied or shown interest in the past waiting to join when jobs come up).
Which leaves big gaps in the rota, it’s usually up to the person who finds themselves working a shift on their own, which ranges from lonely, to difficult, to impossible and occasionally down right dangerous depending on what’s on that day, to beg their colleagues to work over-time to cover it.
I have to assume she’s trying to save costs as often remarks “well, it’s not that busy” if someone finds themselves alone in work.
Still, no one’s died, yet. It’s a distinct possibility though.
