Carthusians:

For the converse nuns, the Cellaress is, in the first place, an example – for actions are more persuasive than words – and they will willingly imitate the Cellaress if she herself imitates Christ. It is chiefly in the domain of work that she carries out her function: she is concerned with the obediences, and is attentive not to overburden her sisters. So that they may dispose of sufficient time for recollection in cell, their daily work period should not normally exceed seven hours. With regard to the converse nuns’ health, the Cellaress will be attentive and full of charity.
