Collective bargaining could also be defined as negotiations relating to terms of employment and conditions of work between an employer, a group of employers or an employers' organization on the one hand, and representative workers' organizations on the other, with a view to reaching agreement.
Emboli, embolus. Plural of embolus. An embolus is something that blocks the blood flow in a blood vessel. It may be a gas bubble, a blood clot, a fat globule, a mass of bacteria, or other foreign body. It usually forms somewhere else and travels through the circulatory system until it gets stuck.
In arterial emboli, blood flow is blocked at the junction of major arteries, most often at the groin, knee, or thigh. Arterial emboli are generally a complication of heart disease. An arterial embolism in the brain (cerebral embolism) causes stroke, which can be fatal.
