Twenty-one employees hold different designations in a bank: CEO, MD, DGM, AGM, Manager, and Clerk, ranked from senior-most (CEO) to junior-most (Clerk). The number of employees at each designation is one more than the designation immediately senior to it. For example, if there are 3 AGMs, then there are 4 Managers, and so forth. Employees P, T, and W share the same designation. S is senior to W. X is senior to U, who is not an AGM. R and V share the same designation. Neither B nor H is a Manager, but both share the same designation. D, E, and H share the same designation, which is junior to Q and T. Q is junior to U. The number of employees senior to Q equals the number senior to T. X is junior to N but senior to R. A, L, and M share the same designation. W is not a Manager. R is neither Manager nor Clerk. Z and Y are senior to G and O.

These employees are transferred to three departments: HR, Marketing, and Legal, based on the following rules:

I. The top two designations (CEO and MD) remain in their posts and become leaders of HR, Marketing, and Legal departments respectively, assigned alphabetically.

II. Employees whose names start with a consonant before 'M' in the alphabet are transferred to HR.

III. Employees whose names start with a consonant after 'M' in the alphabet are transferred to Marketing.

IV. The rest are transferred to Legal.

Based on this information, answer the following question:

Who among the following works with M?
