A 32-year-old pizza delivery driver has been jailed for two years and faces possible deportation to India after he slashed two of his colleagues with a meat cleaver following a work-related argument in Perth's east.

Rajat Chaudhary, a sausage factory worker by day, was angered when one of his Dominos colleagues phoned and threatened to bash him if he didn't comply with a rostering instruction on March 4 last year.

Rajat Chaudhary could be deported after being jailed for two years for attacking his colleagues with a meat cleaver.

The District Court of WA heard Chaudhary went home to collect the cleaver then used it to inflict deep wounds to the two colleagues during a fight outside the Swan View store, where the victims were loitering despite not working at the outlet that night.

Judge Simon Stone said the provocation was minor compared to Chaudhary's reaction.
