At individual contributor level, such schemes may work -- anyways, people are paid by the hour so anything outside hours is already dubbed 'overtime', and companies are bound to care.
At management level (i.e. top management talking either between them or with the management levels just below), where hours don't get counted (in some countries such as France, it's just 'days'), it really boils down to the top management's culture. Workaholic top management = every manager is expected to be workaholic... and Darwin does the rest: soon enough, only workaholics remain.
