fake nails vs work!

Who knows
I am a causal in hospitality and a part time in business admin. 
Business admin is fine with fake nails/ nail polish... 
But hospitality I'm most worried about! 
I wear gloves anyway but I just am worried the oil/heat and moisture that builds up in gloves would ruin my nails.... 
Would it? 
And what length do you think is acceptable 😩 
Help a girl out please!!!
