As noted above, one of the conditions for full furlough is that an employee cannot do any work for their employer during the furlough period. However participating in a grievance or disciplinary hearing is unlikely to amount to ‘work’, and that such participation should therefore be possible while the employee is on full furlough/during their furloughed hours on flexible furlough. Note that, in practice, a fully furloughed employee might simply refuse to engage in the process at all.
