It is 'necessary' to have a good 'atmosphere' at 'work'. 'Work' reminds me of 'colleagues'.Seasick reminds me of heaves, which reminds me of a sign I sometimes see on a road, "Frost Heaves". I never knew what it meant (the poet Robert Frost has gotten sick on this road??) . Now that I've looked it up, it says that frost heaving "results from ice forming beneath the surface of soil during freezing conditions in the atmosphere". So there you go....
