I work in the NHS. We have a crisis at work where amongst our admin team some have been starting work early and leaving late to accrue TOIL. It seems no one has authorised this. They add up all their accrued time and then take the odd Friday and Monday off. Their manager is reluctant to police this and doesn't want to get involved (incompetent) and it is creating huge resentment.
AIBU to think this is unfair on others who do their work in the allotted time.
