**Solution:**

1. The original word is **WORKSHOP** with letters at positions:
   - 1: W
   - 2: O
   - 3: R
   - 4: K
   - 5: S
   - 6: H
   - 7: O
   - 8: P

2. According to the rule:
   - Letters at **odd positions** are replaced by their immediate **next** letter in the alphabet.
   - Letters at **even positions** are replaced by their immediate **previous** letter in the alphabet.

3. Apply the changes:
   - Position 1 (W): next letter is **X**
   - Position 2 (O): previous letter is **N**
   - Position 3 (R): next letter is **S**
   - Position 4 (K): previous letter is **J**
   - Position 5 (S): next letter is **T**
   - Position 6 (H): previous letter is **G**
   - Position 7 (O): next letter is **P**
   - Position 8 (P): previous letter is **O**

4. The new word formed is: **X N S J T G P O**

5. Check for repeated letters:
   - Letters are X, N, S, J, T, G, P, O
   - None of these letters repeat.
