In Swales, the Fifth Circuit Court of Appeals set out to clarify the “legal standard that district courts should use when deciding whether to send notice in an FLSA collective action.” Expressly rejecting the two-stage process described above, the Fifth Circuit clarified that: “Two-stage certification of § 216(b) collective actions may be common practice. But practice is not necessarily precedent. And nothing in the FLSA, nor in Supreme Court precedent interpreting it, requires or recommends (or even authorizes) any “certification” process.”
