Concept:
In Indian industrial labour terminology, “Badli Workers” are substitute workers employed temporarily in place of permanent workers who may be absent due to leave, illness, or other reasons.
The term “Badli” literally means “replacement” or “substitute.”
Step 1: Understanding Badli Workers
Badli workers are:
• Temporary substitute workers
• Employed in place of permanent workers
• Usually not entitled to the same benefits as regular employees
• Common in factories and industrial establishments
Thus, they act as replacement labour whenever needed.
Step 2: Analyzing Option (A)
Option (A) states:
\[
\text{Workers who substitute regular permanent workers \& are contract workers}
\]
This correctly describes the role of Badli workers because:
• They are substitute labourers.
• Their employment is temporary and conditional.
Hence, Option (A) is correct.
Step 3: Examining the incorrect options
Option (B): Permanent workers with full benefits
Badli workers are not permanent employees and generally do not receive complete employment benefits.
Hence, this option is incorrect.
Option (C): Workers with equal status as permanent workers
Badli workers do not enjoy equal status, security, or privileges.
Therefore, this option is incorrect.
Option (D): Home-based piece-rate workers
Home-based piece-rate workers are individuals paid according to units produced at home.
This is unrelated to Badli labour.
Hence, this option is incorrect.
Step 4: Final conclusion
Thus, the most appropriate definition is:
\[
\boxed{\text{Workers who substitute regular permanent workers \& are contract workers}}
\]
Therefore, the correct option is:
\[
\boxed{(1)}
\]
