indispensable definition
indispensable means a duty ‘[t]hat cannot be dispensed with, remitted, set aside, disregarded, or neglected.’” Id. (quoting 5 Oxford English Dictionary 219 (1933)). “An activity is therefore integral and indispensable to the principal activities that an employee is employed to perform if it is an intrinsic element of those activities and one with which the employee cannot dispense if he is to perform his principal activities.” Id. As discussed below, however, the Supreme Court has questioned over broad definitions of what qualifies as an employee’s principal activities. See IBP, Inc. v. Alvarez, 546 U.S. 21, 40– 41 (2005) (citing Steiner v. Mitchell, 350 U.S. at 247) (“[T]he fact that certain preshift activities are necessary for employees to engage in their principal activities does not mean that those preshift activities are ‘integral and indispensable’ to a ‘principal activity’ under Steiner.”).
indispensable means that the intended purpose of the experi- ment cannot be realized with other methods or procedures.303 The law demands use of available alternative methods that do not harm ani- mals, including those that do not involve animals or that lessen the harm to animals qualitatively or quantitatively.304 Animal experi- ments are not indispensable merely because they are cheaper or less time-intensive than available alternatives.305 The applicant must ei- ther demonstrate that the result is unknown or verify a known result. Thus, if the expected or known results do not yield new insights, the experiment is likely not necessary.306
