i believe furlough is a nice concept
been there too
i remember it can be mandatory or not, depending countries (means country laws)
that said if your management is pushing you on this ... can be tough to refuse
some way to convince people is to suggest people not taking furlough would be last ones to get salary review (if applicable) or first one to leave (if applicable)
eventually ; please consider CEO / LT huge need for bonus;
then it makes sense to give them our days off , every buck counts .. :-)
