Give examples where an unresolved labor dispute led to dire social and political consequences.

If a solution to the labor dispute is not found, the labor collective has the right to strike.
A strike is a temporary voluntary refusal of employees to perform their labor duties (in whole or in part) in order to resolve a collective labor dispute. The decision to strike is taken at the general meeting of the labor collective by at least two-thirds of votes.
The administration must be warned about the strike in advance – no later than two weeks before it starts.
None of the collective members can be forced to participate in a strike or to refuse it. During a strike, its participants do not receive wages. In the process of resolving a collective labor dispute, including a strike, the so-called lockout is prohibited – the dismissal of employees at the initiative of the employer in connection with their participation in a collective labor dispute or strike.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
