When disciplining employees for mild infractions, Rita begins with an informal discussion with the employee about the infraction
bulgar [2K]

Answer:

The correct answer is: Progressive Discipline.

Explanation:

Progressive discipline is a process or system of discipline that is commonly used in workplace settings in which the punishment or penalty for unwanted behavior increases in severity each time the behavior is repeated by the employee.

Usually, the first penalties are conversational, such as informal discussions about the infraction, but can escalate to disciplinary layoffs and discharges.

In this particular case, Rita begins the progressive discipline process with an informal discussion but if the problem continues Rita resorts to more serious forms of discipline. The discipline process that Rita follows is referred to as Progressive Discipline.

Explain how mining positively and negatively impacts local communities
Mars2501 [29]

Answer:

The positive impacts are simple- jobs. Mining, drilling, and other exploratory resource harvesting companies have historically brought abundant employment opportunities. They can also revive dying towns/cities that are the brink of financial ruin.

The negative impacts however, are sometimes far greater dependent on the type of operation, and the environment in which these operations take place.

Example: while the pebble mine in Alaska gives abundant employment and financial benefit to those that take part in it, the estuaries of which Salmon have used those streams for a millenia are threatened by the toxic drainage. If this operation is regulated carefully, an entire link in the environmental cycle there can be broken and could have devastating long term impacts on the entire area and surrounding communities.
