Step 1: Identify the most immediate and logical first action.
Before taking any action against an employee, a responsible manager must first confirm the claims. Marathe has received reports about Kale's behavior from Bhonsle and Gore. The most critical and immediate step is to investigate and verify these facts. [2] This makes action (2) the clear starting point for any fair process. Actions like transferring, sacking, or demoting without verification would be premature and unprofessional.
Step 2: Determine the appropriate mid-term solution.
Once the facts are verified, the next step is to address the workplace problem. Sacking (3) and demoting (4) are harsh, punitive measures that should be a last resort, especially since Kale is described as "conscientious and dedicated" when working alone. Transferring Kale (1) to a solo researcher role in the Chennai office is a constructive, mid-term solution. It resolves the team conflict in Mumbai while placing Kale in a position that aligns with his strengths.
Step 3: Identify the long-term, supportive solution.
The passage indicates that Kale has significant personal problems (an ailing wife and a difficult family situation), which could be the root cause of his workplace behavior. Addressing this underlying issue is a long-term strategy for employee well-being and rehabilitation. [8] Suggesting a family counselor (5) is a supportive, long-term measure aimed at helping Kale manage his personal stress, which could, in turn, improve his professional conduct.
Step 4: Form the sequence from immediate to long-term.
The logical order of operations is: First, investigate the claims. Second, implement a practical solution to the immediate work environment problem. Third, offer support to address the root cause for long-term improvement. This creates the sequence:
Immediate: (2) Verify the facts.
Mid-Term: (1) Transfer Kale to a suitable role.
Long-Term: (5) Suggest counseling.
This corresponds to the sequence 2, 1, 5.
Therefore: The most appropriate sequence of decisions is 2, 1, 5. \[
\boxed{\text{2, 1, 5}}
\]
