Metro is forcing train drivers to attend company-endorsed medical clinics for work-related injuries, leading to claims staff are being intimidated and threatened with disciplinary action if they choose their own doctors instead.

The new rules have been so fiercely enforced that a female train driver recently locked herself in a toilet cubicle to phone for help after she was allegedly approached by two Metro officers while at her personal doctor's clinic in Frankston.

Melbourne's rail operator introduced its new policy in March for drivers who sustain physical injuries on the job and shock or trauma from near-miss collisions, according to a memo from Metro management obtained by The Age.

But the directive has raised concerns over allegations of intimidation and employment policies that infringe on workers' private lives and personal choices.
