"Why lawsuits against COVID-19 vaccine mandates will likely fail: Experts", 8 Oct 2021

…[P]laintiffs [who have sued employers’ vaccination requirements]… have argued that the mandates should be removed, questioning the rules' constitutionality and some contending their religious rights weren't observed.

So far, these arguments have not swayed judges who have almost all ruled in favor of the employer, or not issued long injunctions while they hear the case…

… [S]trong legal precedent dating back to the early 20th century gives businesses and governments the legal backing to enforce the mandates.

… [T]here is a potential court battle over how businesses accommodate religious exemptions for vaccinations because that issue hasn't been settled in the Supreme Court.

… [A] July 2021 ruling by the Department of Justice's Office of Legal Counsel… gave businesses the legal backing to invoke a COVID-19 vaccine mandate for their employees.

… [P]ublic and private employers have provided leeway for their members to get religious and medical exemptions, and for the most part have been accommodating.

[Cases have] not cover[ed] religious exemptions and the Supreme Court has yet to rule on how those exemptions play out with vaccine mandates…

… [T]he issue of religious exemptions will eventually reach the Supreme Court, but it's hard to know if the court will review a case. Last week, the Supreme Court denied a request by New York City education employees to hear their case against the city's vaccine mandate after several lower courts ruled against the plaintiffs.
