Amazon’s efforts to deal with COVID-19 at its warehouses haven’t been enough to sway at least some workers. The labor union Verdi has announced that staff at six sites in Germany will strike for a minimum of two days over a claimed lack of transparency regarding infections. There had been “at least 30 to 40” workers infected, Verdi representative Orhan Akman told Reuters, arguing that Amazon valued profits over safety.

We’ve asked Amazon for comment. In a statement to Reuters, it denied that it didn’t prioritize safety and pointed to $4 billion in safety measures for both employees and customers.

The service did say it had sourced hand sanitizer that would ship next week, but workers saw this as indicative of Instacart dragging its heels. Shoppers said they had been asking for sanitizer for “many, many weeks,” but the company was only now conceding to this demand.

We’ve asked Instacart for comment on the decision to continue with the strike.

It’s not certain how many workers are participating in the measure, but it might have a tangible impact. Instacart is already struggling to cope with the surge in demand from customers determined to avoid grocery store trips that could increase the risk of virus infections, and losing even some of those workers to a strike could exacerbate the situation. The question is whether or not the impact will prompt further changes, especially when Instacart has upward of 300,000 new workers on the way.

Among their demands, Instacart Shoppers are requesting protective supplies like hand sanitizer and disinfectant wipes. They’re also asking for hazard pay — an additional $5 per order — and an extension of pay for workers impacted by COVID-19.

The deadline to qualify for those benefits was originally April 8th, but the company has pushed that back through May 8th. Today, Instacart also announced bonuses, based on the numbers of hours worked and ranging from $25 to $200.

“Instacart has still not provided essential protections to Shoppers on the front lines that could prevent them from becoming carriers, falling ill themselves, or worse,” Shoppers wrote. “…They are profiting astronomically off of us literally risking our lives, all while refusing to provide us with effective protection, meaningful pay, and meaningful benefits.”

Instacart, like Uber and Lyft, has said it will provide workers who contract COVID-19 or are forced to quarantine with two weeks of pay. It has also introduced no-contact deliveries. But workers say this is not enough. At the same time, the company is struggling to keep up with demand, and earlier this week it said it will hire an additional 300,000 “full-service” contractors.

The cut comes shortly after thousands of Instacart shoppers participated in a three-day strike over the default tipping option. The app sets the base tip to 5 percent rather than the earlier 10 percent, and workers argue that this has cut into their practical income. Some shoppers, including strike organizer Vanessa Bain, have called the end of the quality bonus a “retaliatory” act meant to punish workers demanding better conditions.

In a response, Instacart told Engadget that the decision wasn’t related to the strike. It also pointed to a segment in the email indicating that this “will not impact the earnings structure and minimums [Instacart] committed to earlier this year.” It argued that there was another incentive in priority access to batches for well-rated shoppers, although that doesn’t increase pay by itself.

Regardless of any connections or alternative incentives, the decision could significantly cut into earnings. Bain said that the bonus can represent as much as 40 percent of pay, and that veteran couriers have grown to depend on it. Without that bonus, Instacart may have a harder time keeping experienced shoppers as well as those who rely on the service as a major source of income. It also fuels worries that gig economy companies are continuing to squeeze their rank and file in a bid to boost profits without raising prices.
