NURREMBERG, Germany (AFP) — Seated before the tram’s control panel, Benedikt Hanne, 24, deftly steered the red and white wagons, hours before heading to Nuremberg university to study for a social work degree.

As an apprentice, Hanne was watched closely by a trainer, and the tram he drove had no passengers.

But if all goes well, he will soon become a fully-fledged tram driver moving people across Nuremberg in the evenings or at weekends, when he does not have classes to attend.

Squeezed by a serious manpower shortage, public transport operators like Nuremberg’s city service VAG have had to find new sources to expand their pool of workers.

The VAG needs to recruit 160 new drivers annually to run its metro, trams and buses.

For Harald Ruben, who heads the company’s recruitment and training team, it was clear that “we won’t reach this target unless we explore all possible possibilities.”

The transport company put out an advert targeted at university students, offering a part-time job to drive trams outside school hours.

To qualify, they need a regular driver’s license, be above 21 years of age, and be “reliable and suitable for driving and shift work.”

Many sectors in Germany, like other European countries, are suffering from a serious manpower shortage which is expected to worsen unless urgent measures are taken.

Public transport operators have warned they may have to reduce the number of buses, trams or metros as tens of thousands of jobs are expected to remain vacant in the coming years.

The worker gap has led public transport employees across the country to go on strike in the last weeks to underline their plight, with union Verdi warning of deteriorating conditions.

Many operators are reporting up to 20 to 30 percent unfilled posts, with shortages contributing to a vicious circle of overworked employees who are then falling ill, exacerbating the situation.

Other German cities like Mannheim and Munich have also begun tapping students as potential part-timers to fill public transport gaps.
