This fact shows suppression of bone marrow activity, as a hematological sign specific for pernicious anemia and radiation sickness.A leukocyte count above 25 to 30 × 109/L is termed a leukemoid reaction, which is the reaction of a healthy bone marrow to extreme stress, trauma, or infection. It is different from leukemia and from leukoerythroblastosis, in which either immature white blood cells (acute leukemia) or mature, yet non-functional, white blood cells (chronic leukemia) are present in peripheral blood. Classification
Leukocytosis can be subcategorized by the type of white blood cell that is increased in number. Leukocytosis in which neutrophils are elevated is neutrophilia; leukocytosis in which lymphocyte count is elevated is lymphocytosis; leukocytosis in which monocyte count is elevated is monocytosis; and leukocytosis in which eosinophil count is elevated is eosinophilia.An extreme form of leukocytosis, in which the WBC count exceeds 100,000/µL, is leukostasis. In this form there are so many WBCs that clumps of them block blood flow. This leads to ischemic problems including transient ischemic attack and stroke. Causes
Leukocytosis is very common in acutely ill patients. It occurs in response to a wide variety of conditions, including viral, bacterial, fungal, or parasitic infection, cancer, hemorrhage, and exposure to certain medications or chemicals including steroids.
It can still be ended for two reasons: personal reason, immediate end of employment only for strong reasons such as crime, or lack of work tasks (swe: Arbetsbrist), cancellation of employment, usually because of bad income for the company. There is a cancellation period of 1–6 months, and rules for how to select employees, basically those with shortest employment time shall be cancelled first.There are no laws about minimum salary in Sweden. Instead, there are agreements between employer organizations and trade unions about minimum salaries, and other employment conditions. There is a type of employment contract which is common but not regulated in law, and that is Hour employment (swe: Timanställning), which can be Normal employment (unlimited), but the work time is unregulated and decided per immediate need basis. The employee is expected to be answering the phone and come to work when needed, e.g. when someone is ill and absent from work. They will receive salary only for actual work time and can in reality be fired for no reason by not being called anymore. This type of contract is common in the public sector. United Kingdom
In the United Kingdom, employment contracts are categorized by the government into the following types:
Fixed-term contract: last for a certain length of time, are set in advance, end when a specific task is completed, ends when a specific event takes place. Full-time or part-time contract: has no defined length of time, can be terminated by either party, is to accomplish a specific task, specified number of hours.
