And I would add that most likely, drug reps are NOT going to like the "fun".
If the Supreme Court justices decide in favor of the rep's, then that means the rep's just became non-exempt employees as opposed to the exempt employees they are today. Pfizer might cut their salary as a result of that. Ask yourself this question: Why in the world would it make sense to Pfizer management to keep paying a rep an exempt salary, when they are now considered to be a non-exempt employee and should be paid OT for all hours worked in excess of 40? Think I'm crazy? I saw that very thing happen at IBM, and it was to the tune of a 15% cut in pay.
Sure, you might get a lump sum cash distribution from the lawsuit, and it might be in the thousands of dollars. (As was the case at IBM) But if your pay is cut, and you're told not to worry, that you can make it up by working OT, what will you do when they eventually say "Nobody will work OT" which is what they also did at IBM.
