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.
More important, treatment is necessary to prevent a clot in the legs or pelvis from breaking up and traveling to the lungs. If those clot pieces, called emboli, lodge in the lungs, they can prevent those organs from getting enough oxygen-carrying blood, killing tissue, and making it hard for you to breathe. Left untreated, pulmonary emboli kill about 30 percent of people who experience them.
