Why dont bloke agers exploit relationships instead of condemming them?

Why dont managers exploit relationships instead of condemming them.by this i mean instead of being cross why not get sneaky as say.if you two get your quotas done on time or quicker or sell extra stuff or sort something out to a higher standard..15 minutes in the paper cupboard..then let them flirt/ wear sexy stuff.surely efficency would go up 500%er some confusion here.suggesting managers see staff falling in love as an opportunity to get the staff to work harder and have fun with being allowed to have a make out session as the incentive.then letting them flirt to increase said urgency to get the job done.;ie instead of scaking staff who date let them kiss.. if they get the job done
