(Yesterday, 9:27 am)Storx wrote Arriva down there are cancelling buses on a daily basis lately as they don't have enough drivers to do the normal work and are as always relying on overtime which is bad practice.
Stuff like this is where overtime should be used, not running a normal service.
All bus companies rely on overtime to cover their 'normal service', if you think they don't you're living in dreamland.
Sickness? Overtime. Holidays? Overtime. Disciplinary action? Overtime. The list goes on.
