Employers should always make sure employed musicians’ instruments and equipment are safe. This means employers must take steps to protect the instruments from damage and theft. An employer only needs to take reasonable and necessary precautions. The law does not require employers to safekeep with 24-hour armed security and bank vaults. For example, an employer might lock up the instruments at night, make sure the building is secure, or keep an eye on who comes in and out of the area.
If a musicians equipment gets damaged or stolen because an employer fails to take reasonable and necessary precautions, then the employer is responsible to pay for the repair or replacement. An example of unreasonable precautions might be if the employer leaves the building where the musical instruments and equipment are kept unlocked.
