(CNN)In March 2020, Europe's towns, cities and airports ground to a halt as the first wave of Covid-19 sent residents indoors. In the following months, many people began working from home. But amid the chaos and uncertainty, key workers including farm staff, transport employees and postal workers continued to perform their jobs as normal, forming an often invisible frontline during the pandemic.

Here are some of their stories.

A farm worker in Britain

    Ingrida Bernotiene lives and works on a salad farm in Kent, southeast England.
      The 33-year-old is originally from Lithuania and started working in agriculture aged 20, as a seasonal worker. She is now a production manager and helps oversee seasonal workers in the fields.
      Bernotiene has worked throughout the pandemic, often spending whole days outside checking crops.
      England entered its first national lockdown in March and a second one in November. The UK has been one of the worst-hit countries in Europe, with a tally of more than 71,000 deaths linked to Covid-19, according to Johns Hopkins University. But farms have continued to operate, in a crucial effort to maintain food supply.
      "We were working day by day, six days a week [in the summer]," Bernotiene told CNN, adding that her schedule had been unaffected by the pandemic.
      "And [we] usually start at 5 am and finish at 4 pm, and [have a] one-hour break. We didn't really feel [scared] much because we feel quite isolated here, [as] this farm is in the middle of the fields."
