Greetings:
Yes, second hand marijuana smoke can show up on a urine test...(it leaves traces of THC)... It will produce a positive result on the first day or so after breathing in the smoke.
Please see the following:

Go Ask Alice!: Second-hand marijuana smoke and drug tests
Marijuana.Com Marijuana Seeds & Drug Test Information
Since you are needing to take a drug test for work - just stay away from others who are smoking.
Please take care.
Bright Blessings.
Peace, Love & Happiness,
