Tata Consultancy Services (TCS) is implementing a mandatory COVID-19 vaccination policy for all employees, with a deadline for the first dose. Those who refuse vaccination must submit weekly, non-reimbursable RT-PCR tests. An employee with high antibody levels is seeking advice on the legality of this policy, questioning if it's permissible to force vaccination or weekly testing. The general consensus suggests that companies can enforce such policies in the interest of employee safety, and legal challenges may not be successful.
