German supermarket chain Aldi has become the latest firm in the grocery sector to offer incentives for United States employees getting a Covid-19 vaccine, saying it would give up to four hours of pay to those who choose to receive inoculations.

The retailer, which has more than 2,000 stores in 37 US states, said it would cover costs associated with vaccine administration and implement on-site vaccination clinics at its warehouse and office locations, Reuters reported.

Aldi said it was working with officials across the United States to get workers priority access to the vaccine, joining other companies including Amazon.com Inc and Uber Technologies Inc lobbying to move workers closer to the front of the line for vaccinations.
