You try to tell people There's gonna be cancellation to service and look what happens. Your (the bus company) made out to be the bad person

Poor management, low pay, naff conditions and an industry which has traditionally had high turnover. 
Nobody could have predicted the pandemic, but they could have done so much more to ensure that staff turnover was lower prior to it and that drivers didn't move on.

Remember, this is an industry which is down sizing on a regular basis. Routes are consolidated, fleets are made smaller - but recruitment events are held, training fleets are out on the road and pushed to the limits. Those recruitment and events and training fleets wouldn't need to exist if the staff turnover was low.

Operators have been caught with their pants down during the pandemic and haven't been able to stem the usual flow of leavers, with new recruits.
It's as simple as that.
