Types of Strikes
Sit down Strike
Slow Down Strike
Union members sometimes try lesser degrees of workplace disruptions before they resort to an all-out strike:
Sick-out (or sick-in) - All, or a significant number of union members call in sick on the same day. They haven't broken any rules, because they just use sick leave that was allotted to them. However, the sudden loss of so many employees all on one day can show the employer just what it would be like if they really went on strike.
Slow-down - All the union employees continue coming to work on time, and they continue to perform their jobs, but they do them more slowly. This might mean that they start doing everything "by the book," following every guideline and performing every safety check to the point that their work slows down. The resulting drop in production hurts the employer, but again, the employees aren't actually breaking any rules. This is sometimes called a partial strike.
Sit-down strike - Employees show up to their place of employment, but they refuse to work. They also refuse to leave, which makes it very difficult for anyone to defy the union and take the workers' places.
Sympathy strike:An important element of most successful strikes is the sympathy strike. If one union has more power than a single worker, then several unions banded together are very powerful indeed. In a sympathy strike, other unions in the same industry, or employed by the same company, will strike at the same time, putting even more pressure on the employer to resolve the original strike. For example, the failure of the 1980s air traffic controllers' strike was due in part to the union's failure to set up sympathy strikes. The pilots, baggage handlers and flight attendant unions didn't engage in sympathy strikes
General strike-It is one in which all or most workers in an entire region or country go on strike together, regardless of union affiliation. These strikes are usually intended to create political pressure on the ruling government, rather than on any one employer.
Strikes can occur because of the following reasons:
Dissatisfaction with company policy
Salary and incentive problems
Wrongful discharge or dismissal of workmen
Withdrawal of any concession or privilege
Hours of work and rest intervals
Dispute connected with minimum wages
