I'd always be cautious about negatively portraying another law firm or department as a way to justify your motivations for applying as this doesn't convincingly convey what you actually like about the firm or department you've chosen. Accordingly, labelling other practice areas as money centric doesn't actually demonstrate why you like Employment and Labour. As Jessica said above, the human element in the work that you deal with could be a good reason but you need to explore why you like this in further detail- does you work have a more direct impact on human lives, do you feel a greater sense of responsibility and sensitivity in how you approach your work, are there more complexities to consider in this practice area etc.?
