No man is indispensable

Proverbial Meaning: We (your employer) can always get someone else to do your job.

Literal Origins: If a person was indispensable they would not be replaceable, but this proverb suggests that no one, no matter how good they are at what they do, is unique and irreplaceable.

Common Usage: This proverb is fairly well-known and often used in a working environment, especially a high pressure work environment such as a busy corporate office.
